Seed Orders

What’s still green above the snow: Conifers, Apache plume, rose stems, Japanese honeysuckle, columbine, rockrose, coral bell, snapdragon, bouncing Bess, blue flax, sweet pea, yuccas, Mount Atlas daisy.

What’s gray or gray-green: Salt bush, winterfat, buddleia, snow-in-summer, pinks.

What’s red: Cholla.

What’s blooming inside: Aptenia, geranium.

Animal sightings: Early in week, bird tracks in snow-covered beds, rabbit tracks in drive.

Weather: Cold Thursday killed many remaining green leaves; snowed around noon; since then, snow only melted on south side of house and from an exposed east facing bed.

Weekly update: I excuse my late fall laziness by claiming I let plants go to seed to give the best the chance to reproduce. Of course, I don’t rely on nature. So, the snow comes and goes, the birds leave tracks around abandoned stalks, and I spent the holiday reading this year’s batch of seed catalogs and ruminating on the earliest known American seed order, the one shipped in 1631 to Massachusetts Bay and reprinted by Ann Leighton.

When John Winthrop, Junior, bought seeds from a London grocer in July 1631, he, no doubt, had heard from his father, the governor, about the many deaths from cold and malnutrition the previous winter. He chose roots and leafy vegetables he knew would survive cold storage or drying and could be boiled in a single pot. His largest quantities were parsnips, carrots, cabbage, pumpkin, raddish, parsley, lettuce, skirret, and cauliflower.

Many of the other seeds he requested were herbs, like marjoram, basil, and chervil, that were added to the cauldron. Only a few were ornamental plants, perhaps the hollyhocks and stocks, and a very few, like monk’s hood, were exclusively medicinal.

Missing from his shopping list were the crop seeds, the grains and legumes, the wheat, rye, barley, oats, beans, and peas, the staples provided by the Massachusetts Bay Company. Daniel Slade says the proprietors also sent fruit stones; flax, hemp, woad and saffron seed for textiles; potatoes, and hop roots for brewing.

Winthrop’s selection seems commonplace enough. After all, the previous year Francis Higginson had told London that root crops, pumpkins, pot-herbs, and sweet herbs were doing well in Plymouth, founded ten years earlier. A generation later, John Josselyn found more than 40% of Winthrop’s species were commonly grown in Massachusetts.

What seems unusual about Winthrop’s receipt is that he bought ounce and half-ounce quantities of herbs. If he and his wife spent the first winter with his father, there were five adults and five children to feed. 80,000 thyme seeds, 40,000 savory, and 34,000 sorrel, the number offered today in an ounce, seems excessive for ten people, even granting Governor Winthrop was obliged to entertain.

I don’t know if Winthrop did the calculations I do when I plan a seed order, but I convert weight into number of seeds, and then into linear feet to make sure I don’t buy too much. As near as I can judge, adjusting for temporal differences in quality and cleanliness in seed, he would have needed at least five acres to grow all the seed he bought.

His father had more than enough land, certainly more than one of my immigrant ancestors whose three-acre town lot and six-acre crop land grant in Ipswich in 1637 would not have supported all Winthrop’s seed and also produced essential foodstuffs. In 1630, the governor had been granted a seventy-acre island now subsumed into Logan Airport, a 600-acre farm in what is now Medford, and a town lot.

However, like me, young Winthrop did need to consider how all those seeds were going to be planted, weeded, protected from birds, and harvested. The 25-year-old man had no intention of preparing five acres of virgin land himself before spring planting. His great-grandfather Adam, a guild leader in London, had purchased an estate when Henry VIII dissolved the abbey at Bury Saint Edmonds in 1552, his great-uncle John had claimed a plantation in Munster in 1595 when Elizabeth I opened the area to Protestants, and his younger brother Henry had gone to slave-owning Barbados in 1627. His father hired James Luxford a year later to manage the Ten Hills farm and used Indians on the island.

I suspect Winthrop thought he could make money from luxury seeds that were not supplied by the London company, for those were the ones he bought in superfluity. Perhaps he expected to sell some seeds in the spring, perhaps he expected to sell his surplus crop in summer. We know his father expected a profit from his farm because he later claimed Luxford sold the produce at below market prices.

I don’t know if my ancestor resented his dependence on seed and produce merchants, but other commoners rebelled against a profiteering nail importer in 1639. Even though I know I can enjoy the luxury of growing flowers, not vegetables, because entrepreneurs like Winthrop settled Massachusetts in the 1630's, the snow and the birds remind me life still depends on food, warmth, and good seed.

Single-seeded Juniper

What’s still green above the snow: Conifers, Apache plume, roses, hollyhock, columbine, rockrose, coral bell, snapdragon, bouncing Bess, blue flax, sweet pea, yuccas, Mount Atlas daisy.
What’s gray or gray-green: Salt bush, winterfat, buddleia, snow-in-summer, pinks.
What’s red: Cholla.
What’s blooming inside: Aptenia, geranium.
Animal sightings: Rabbit and bird tracks in snow Saturday morning.
Weather: Cold all week; snow Friday evening.
Weekly update: When I was a child trapped in the backseat on my parent’s weekly shopping expeditions, I would pretend I was in a covered wagon moving west and the fallow fields passing the side window were virgin prairie.
Around the same time, Angélico Chávez was driving along the Rio Grande to La Toma trying to recreate the experiences of Juan de Oñate and the Franciscans who came north with him in 1598. He thought the "hunched junipers and piñons" would remind them, not just of their Estremaduran homeland, but of the olive groves of the Holy land.
I was too young to know the Michigan land had changed several times since whites had intruded in the 1830's. He may not have known single-seeded junipers had been encroaching on grasslands since the suppression of wildfires in the 1880's, and were more common when he saw them than they had been during the entrada.
Ecological facts would not have mattered to either of us seeking an imaginative leap into the past through the only thing that remained, the landscape.
Those who only know the juniper from photographs of perfect specimens would not understand the associations made by a Franciscan scholar born in Wagon Mound in 1910. Our native trees are clusters of gray trunks buffeted by high winds into asymmetric stabiles that rarely reach their full 40' height.
Juniper is one of the first plants to come back after fire, and its deep taproot and supporting surface roots have adapted to drought. Even in the best conditions, it only grows about 6" every ten years, a foot every score. While this Pinaceae may bear fruit when it’s ten years old, its best years come when the gray-green evergreen reaches 50 and last another 150 years.
Juniperus monosperma is more than an indicator plant for vegetation at our elevation between 5,000' and 7,500'. For centuries, the dark purple berries were a staple of the pueblo diet, replaced only when other foods became available. Santa Clara used the wood for bows and digging sticks, bound the shredded bark with yucca for torches. Spanish speakers used sabino wood for ceiling lath.
Hu seeped into Santa Clara ritual life where Robbins and Harrington heard juniper branches were substituted for the preferred spruce in dances, while women purified themselves the third day after childbirth with bath water infused by the fleshy, flat leaves.
To the west, Zuñi women drank hot tea of toasted twigs and berries during labor. Spanish-speaking women in northern New Mexico sipped a half-cup each morning during the last month of their pregnancies brewed from the herringboned branch tips.
Now winter has set in, the only green I see from my window is the scrubby juniper where the quail run for shelter. When I walk out, all I see are green bumps on the ranges rippling away from the river and arroyo. Even though I know the trees have probably only grown since the ranch beyond ceased operations, there is still something elemental about the dark dervishes clinging to the earth like Franciscans called to matins by Chávez’s hero, Junípero Serra.Notes:Chávez, Angélico.

Saint John's Wort

What’s green above the snow: Conifers, grasses, Apache plume, roses, Japanese honeysuckle, hollyhock, winecup, columbine, rockrose, coral bell, snapdragon, bouncing Bess, blue and yellow flaxes, sea pink, yellow and pink evening primroses, vinca,, sweet pea, yuccas, red hot poker, iris, Saint John’s wort, anthemis, Mount Atlas daisy, Mexican hat, purple aster.

What’s gray or gray-green: Salt bush, winterfat, buddleia, loco, snow-in-summer, pinks.

What’s red: Cholla, soapwort.

What’s blooming inside: Aptenia, geranium.

Animal sightings: Bird tracks.

Weather: Snow Monday and Friday; ground frozen and heaving under gate.

Weekly update: It’s a week until the winter solstice, and the cold of winter has already set in. Almost everything has been buried by snow at least once this week, but one emblem of Midsummer’s eve, Saint John’s wort, poked through the icy crystals with tinges of red on the edges of its green, ovate leaves.

When I bought Hypericum perforatum in 2000, the store posted a warning it could become invasive. Since so few things grow in my garden, I thought it would be nice to have something that would fill in dry areas beyond the hoses, especially if it covered itself with bright five-petaled flowers.

Alas, my Helos cultivar has only bloomed three times, and then, rather than bouquets of stamens standing high above large, butter-yellow pads, the plants produced chartreuse tips. If any flowers were there, they were too insignificant to see.

However, as promised, it did spread.

I decided to move the plants from my front garden to an area where anything green was welcome, and discovered the rust-colored, serrated stems stood ready to protect their position. Whenever my arm brushed them, it started to itch. The likely cause is hypericin, a napthodianthrone that collects in the dark oil glands on the flowers and leaf margins.

That red chemical is the reason Saint John’s wort became commonplace after people with AIDS claimed it was a possible cure. Scientists have since found it is effective against T-cells and cancerous cells, but haven’t yet found a way to make it reliable enough to prescribe.

Maria Leach suggests this particular Hypericum species arrived in England with the crusaders who found it healed wounds in the middle east. In 1597, John Gerard still recommended using leaves, flowers and seeds soaked in olive oil to close cuts, a remedy repeated by Nicholas Culpepper in the 1650's.

Germans treat depression with hyperforin from the translucent leaf glands. This practice may be an extension of the traditional belief that it thwarts demons and counteracts spells, especially during the summer solstice when the spirits are active. The symptoms of the one may well be the same as the other, allowing for changes in language and the metaphors of emotional problems.

James Frazer believed the ancient Druid bonfires in England were the same as those in central Europe on Mid-Summer’s eve, only yellow flowers of mistletoe were collected to heal cuts and cure epilepsy. Saint Patrick is the one credited with substituting the name date of John the Baptist for the pagan rite.

Since I’m not ready to experiment with dosing myself with something that irritates my skin, I have no reason to leave the multi-branched interloper in my front garden. Its eradication is a constant struggle because the woody taproots have runners that break and regenerate.

In a way I’m lucky they don’t bloom. The hermaphroditic flowers are able to produce seed without being pollinated. Once buried, the seed can remain viable for ten years. In California they finally imported beetles from Australia to protect livestock from sickening when they ate it.

Since I’m not willing to combat one invasive species with another that might find other things to eat in my arid environment, I’m left with weeding, itching, and pondering the conflations of hyperforin with hypericin and Christmas mistletoe with snowbound Saint John’s wort.

Western Stickseed

What’s blooming: Sweet alyssum from seed.

What’s still green: Conifers, grasses, Apache plume, roses, Japanese honeysuckle, hollyhock, winecup, columbine, lamb’s quarter, rockrose, California poppy, coral bell, snapdragon, beardtongues, bouncing Bess, blue and yellow flaxes, sea pink, yellow and pink evening primroses, catmint, Rumanian sage, vinca, tansy mustard, sweet alyssum, western stickseed, white sweet clover, sweet pea, sea lavender, yuccas, red hot poker, iris, Saint John’s wort, snakeweed, coreopsis, anthemis, chrysanthemum, tansy, Mount Atlas daisy, Shasta daisy, perky Sue, Mexican hat, purple aster.

What’s gray or gray-green: Salt bush, winterfat, buddleia, loco, snow-in-summer, pinks, fern-leaf yarrow, golden hairy aster.

What’s red: Cholla, soapwort, hartweigii.

What’s blooming inside: Aptenia, geranium.

Animal sightings: Usual red-sided birds and quail continue to feed.

Weather: Cold, clear nights early in the week iced over standing water along the road; more recently, clouds moved in to scatter droplets at sundown; rain yesterday; more rain and a little snow last night.

Weekly update: Whatever is a spring annual like western stickseed doing germinating in my driveway now, when other plants are either going dormant or dying from the cold? Normally, I see the basal rosettes emerge after March 20th and start flowering the second week of April.

It’s a question that puzzles botanists like Kathy Freas and Paul Kemp, who know desert annuals sprout when there’s enough moisture at the right temperature. What they wonder is how does a species survive when a cool temperature plant like Lappula occidentalis germinates just before a drought or severe cold that kills seedlings.

When they compared plants that germinate in the heat of summer when moisture is more reliable in the Chihuahuan desert with those like stickseed, they found the cool-season plants had developed genes that controlled dormancy, while summer plants had not.

Dormancy allows plants to build seed reserves which can sprout when conditions change dramatically. Stickseed is one of the first plants to arrive after a fire, stays long after the soil has been trampled by cattle.

For years, western stickseed pushed up thin stems with tiny, five-petaled, bluish-white flowers. Those stalks would unfurl, much like their forget-me-not cousins, to produce more color on top while hairy, green balls replaced spent blooms. The taproot could send up multiple, sparsely leaved columns, but usually they remained small, delicate plants that crept along the edges of garden beds.

Then, in 2004 the upper yard was covered with clumps where the ground had been disturbed in 2001 to bury a natural gas line. That area had been colonized by muhly ring grass until the drought of 2002-2003. The flowers were equally prolific in 2005, but since, the annuals have put out fewer and shorter racemes.

Perhaps the seed bank has been exhausted, although seeds are the one thing I know have been produced abundantly. The hard, odd-shaped dark seeds start to form in May, and attach themselves to my socks and pant legs in June. They remain a nuisance after the plants have dried into brittle stalks, enough to keep me out of the area where they’re growing and, coincidentally, protect the nearby soil.

It’s just been in the past few weeks, the very time that the vagrants have been growing in my drive, that the dead clumps have disappeared, probably broken off by the high winds and blown elsewhere to drop whatever barbed seeds remain.

The plants may have been shunted aside by snakeweed which also appeared in that area after the drought, and is not polite enough to quietly leave at the end of the season. Or, the tiny Lappula may not have liked the higher levels of rain and snow in the past few years.

It’s impossible to predict what will happens next year; the crop is too dependent of whatever combination of temperature and water exists in early spring. All I can do when I stop to open my gate is look for the white-haired volunteers to see how long they survive the coming cold.

Apache Plume

What’s blooming: Sweet alyssum from seed.

What’s still green: Conifers, grasses, Apache plume, roses, Japanese honeysuckle, hollyhock, winecup, columbine, lamb’s quarter, rockrose, California poppy, coral bell, snapdragon, beardtongues, bouncing Bess, blue and yellow flaxes, sea pink, yellow and pink evening primroses, hartweigii, catmint, Rumanian sage, vinca, tansy mustard, sweet alyssum, white bristle stickseed, baptista, white sweet clover, sweet pea, sea lavender, yuccas, red hot poker, iris, Saint John’s wort, snakeweed, coreopsis, anthemis, chrysanthemum, tansy, Mount Atlas daisy, Shasta daisy, perky Sue, Mexican hat, purple aster, chocolate flower, black-eyed Susan.

What’s gray or gray-green: Salt bush, winterfat, buddleia, loco, snow-in-summer, pinks, fern-leaf yarrow, golden hairy aster.

What’s red: Cholla, soapwort.

What’s blooming inside: Aptenia, geranium.

Animal sightings: More birds than usual on utility line Friday morning when the storm was in the air; flock of small birds in abandoned road bed Saturday morning, probably migrating; quail and red-sided birds in yard, no see-ums; brown goat down the road, horses in the village.

Weather: Cold early in week, snow lingered until rain Friday night; water in the wide arroyo yesterday morning; balmy in the afternoon.

Weekly update: Anyone who has both rented and owned a home knows there is a difference. In both cases, you enjoy the views and interior layout, but only in the one do you become intimately familiar with septic systems and furnaces.

A similar experiential difference exists between growing a plant and seeing it from a car. Take Apache plume. Anyone can enjoy the five-petaled single white flowers and pink, feathery seed heads in summer. But you only see the leaves and stems if you can get close to the loosely-branched shrub.

Many simply say the leaves are tiny or finely divided. In fact, they resemble small hands with narrow lobes that are shorter on the sides than in the middle. They unfurl much like fists, and often remain cupped rather than opening flat. They no only do not upholster the stems, but are neigh invisible from a distance.

When people can’t routinely see something, they tend to see what they expect. Shaw and Monsen observed new leaves emerge on this thornless member of the rose family in mid-April in Boise and expand in mid-May. Many who see the still green leaves in winter assume they are the same leaves.

In fact, my leaves begin to turn yellow in autumn after morning temperatures drop: last year it was early September, this year mid-October, a week after the first severely cold morning. In the past few week new leaves have been developing where the old ones are turning brown. With luck, they’ll remain on the plant.

New leaves do appear in spring, and this past year they displaced tan ones that had persisted through last year’s snows. It could take several years for me to fully comprehend the pattern, because our climate varies so much from year to year. Now I’ve had the shrubs for 18 months, all I know is what to look for.

The plant grows wild here, but it’s taken three tries to find commercial cuttings that would settle in my yard. Even though Apache plume’s a Chihuahuan desert shrub that has expanded its range, it’s still discriminating. When I’m driving, plants appear randomly along the road and across the river near San Ildefonso. In fact, they prefer the edges of arroyos and other run-offs and the ones I see daily are growing along a paved road that crosses a wide arroyo where their dense rhizomatous roots can reach water stored by both.

It’s cultural range is much smaller than its natural one: all the native usages mentioned by Moerman are from New Mexico or Arizona. Many tribes used the straight, slim branches for arrow shafts, but the Havasupai and Haulapai used roots and branches for cordage. Both the Santa Clara, who talked to men from the Smithsonian around 1910, and Spanish-speaking women, who talked with Curtin in the late 1940's in northern New Mexico, used poñil leaves for hair rinses.

Most pueblo people do not mention an association with witchcraft. The Kayenta Navajo of Arizona believed witches used the plant to induce insanity, but local Spanish-speakers mixed dried poñil plumes with other ingredients to counteract illness fomenting magic. Only the Sandia admit their brooms made from Apache plume branches are kept in the house for their "spiritual presence," while others, including the Santa Clara, simply say the brooms exist for outside use.

The difference between a cultural range and a biological one is like that between the renter and the owner, the grower and the admirer. On its own, Fallugia paradoxa prefers life under trees. In return, its branches shelter piñon seedlings and its roots harbor a cancer-fighting species of penicillium.

In the net of civilization, Apache plume’s reduced to an object of beauty by Idaho gardeners and to raw material by Arizona natives. Still, along the Rio Grande where the pueblos and Spanish settlers exchanged beliefs in witchcraft, it’s been absorbed into views of the world and the origin of things bad that are no more public than the tiny leaves alternating along pealing stems.

Catalpa

What’s blooming: Sweet alyssum from seed, purple aster.

What still has leaves that shouldn’t: Spirea, forsythia, beauty bush, weigela; some local cottonwoods, catalpas, Russian olives, weeping willows..

What’s still green and visible above the snow: Conifers, grasses, Apache plume, roses, hollyhock, snapdragon, columbine, bouncing Bess, California poppy, rockrose, pink evening primrose, vinca, sea lavender, yuccas, red hot poker, Saint John’s wort.

What’s still gray-green: Salt bush.

What’s still gray: Buddleia, snow-in-summer, pinks, winterfat.

What’s turning red: Cholla, coral bell.

What’s blooming inside: Aptenia, geranium.

Animal sightings: Quail, small brown birds with light bellies and red sides; gopher active.

Weather: Snow late Thursday night, everything not buried in the morning was wearing a white crown; little melting since.

Weekly update: Nature’s a bit of an exotic dancer. She thrills you with her whirling colors and flourishes. Then, when you think you’ve seen everything, she drops her skirts and you discover what’s been hidden behind her leaves.

Down the road, unpicked apples expose their abstract placement. In the yard, I can see buds for next year’s lilacs and peaches. When I looked at the bare locust tree to see what was still green, I found Doctor Huey roses growing into the branches.

In town, catalpas bloom at slightly different times in June, but now I can find them all by their straight, parallel pods hanging like icicles frozen in the wind. Most lie among other trees and shrubs along property lines extending back from the highway in town where people built after the automobile made that a desirable location. Others dot the farm, village and orchard roads.

I just discovered the tree I planted in 2000 had bloomed this year, and I never noticed: the broad, heart-shaped leaves obscured the flowers, then shrouded three pods. I assumed my tree was still getting established. Joseph Breck warned gardeners in 1851 they didn’t bloom until they were ten to twelve feet tall. Mine, after years of drought and grasshoppers, is still only eight feet high.

I also wasn’t sure if the tree I ordered from an Ohio nursery was the same species that grew in village. The southern Catalpa bignoniodes was discovered in the southern colonies and spread north as an ornamental. Seeds were shipped to England in 1726. It’s still the most common variety in commerce.

The northern Catalpa speciosa was noticed by William Henry Harrison when he was territorial governor of Indiana territory between 1800 and 1812. However, botanists assumed it was simply an ecotype of the familiar southern tree with variations in habit attributable to differences in climate and soil. While scientists didn’t separate the two until later, Harrison took seeds back to Cincinnati where they spread through Ohio at the same time other settlers were bringing southern seeds in from the east.

Herbert Roberts suggests the easiest way to distinguish the two is by their bark: speciosa is furrowed, while bignoniodes has a scaly, pealing outer surface. The leaves of the one have a more pointed tip than the other. His photographs suggest the parallel, diagonal pods I see in town appear on northern trees while my crooked pods are found on southern ones.

I planted mine because I liked the white flowers that floated above new leaves. I’m not sure why others here grew a tree associated with the rich bottom lands of the Wabash and central Mississippi rivers. In Ohio, they were valued for fence posts, because the wood doesn’t rot in the ground.

In 1902, Roberts was suggesting the northern species be grown for rail ties in notoriously treeless Kansas. At that time, the Rio Grande Western was growing 60,000 saplings as an experiment in Provo, Utah. The year before, that rail line had merged with the Denver and Rio Grande which had reached our valley in 1880. It’s possible some railroad gandydancer brought northern seeds to town.

More likely, they were simply an ornamental grown to beautify the main road to Santa Fe after World War II when traffic picked up and people finally had some extra cash, as well as exposure to landscape design in other parts of the country where they’d been stationed. The use among other trees or shrubs is the one suggested by Breck a century before, perhaps because catalpas grow best in some shade.

Reliable as they may be when they’re converted into lumber, alluring as they may be in bloom, they are still a tease. Every year they grow in late summer. Every year their terminal buds are killed by cold. Every year, you must wait to see it they survived, for they are the last tree to leaf in spring. And then, this year, nature concealed my flowers and pods until she resumed her danse de la vie.

Russian Olive

What’s blooming: Coral bell, snapdragon and sweet alyssum from seed, chrysanthemum, purple aster.

Inside: Aptenia, geranium; coral honeysuckle putting out more new leaves.

Animal sightings: Small birds flit from peach to catalpa and beyond

Weather: Cold mornings with the smell of wood smoke, warm afternoons; last rain, 29 September.

Weekly update: Tis the fickle time of year when warm afternoons belie cold mornings and you can’t tell if a flower is real or a desicated shell of itself. Unsheddable dead leaves, most brown, stay on trees. Cherries and spirea remain shades of scarlet, but it’s impossible to know from a distance if they’re shriveled or whole.

Russian olives clasp dry, grey-green leaves, but I have one with a few narrow willow-type lances still turning yellow. Nearer the river, some trees looked untouched yesterday by last Thursday morning’s cold.

Elaeagnus angustifolia is an anomalous presence, a silvery fruit that’s not an olive, but an oleaster, an import from Europe that’s filled open gaps along the river. Mennonites who fled Prussian conscription for the Ukraine in 1789, spent years learning dryland farming and the value of windbreaks. When Russia threatened conscription in 1880, many migrated to the opening wheat lands of our plains and brought with them both the idea of a shelter belt and Russian olives. They arrived in South Dakota in 1874; in 1901, the state Agricultural Experiment Station issued a bulletin from Niels Hansen promoting the ornamental species.

Cuttings spread among Mormons in Arizona and Utah, and were growing in Mesilla Park in 1903 where New Mexico State was developing its new horticulture farm. Elmer Wooten and Paul Standley reported trees in several places in the state in 1915, but it didn’t naturalize along the middle Rio Grande until dams were completed at Elephant Butte in 1916 and Cochiti in 1975.

Some despise it as a reminder of what has been lost along the rivers. But, if home landscaping reveals anything about our views of an ideal natural world, then some here associate the trees with the river they knew as children. Two of the ten owners of ambitious homes built since I moved here in 1991 have planted Russian olives.

Their unconscious ideal may be a pink adobe set far back from the farm road sheltered by cottonwoods. While the back is now wild wood, the front is dominated by two large specimen Russian olives, one on each side of a bare yard so flat it has to have been leveled by flood irrigation. Grassland expanding out from the homestead to the road is all that remains from the agrarian past, and yesterday that green had retreated to the protection of the trees.

The new home owners differ from the traditional one because they no longer can afford to be open to strangers who use the main road. Their trees screen their houses from unseemly prying. But like the person who imposed formality of the rural land, these people didn’t act on some impulse in the local hardware. Russian olives can no longer be sold in the state. They went to some trouble to find and transplant thorny saplings to places where they could be seen from front windows.

Why? Perhaps because the airy placement of leaves with grey-scaled underbellies along dark curving boughs contrasts with the more somber cottonwoods in the drought of summer. Maybe, the fragrance from tiny yellow flowers in spring promises the return of life flowing from its nitrogen fixing roots. Even now, the spectral leaves sheltering green grass give hope that wintry cold may be delayed.

These images of the past, the future, and the river may be as illusionary as today’s freeze dried leaves, but they’re woven into life in a forever changing river valley.

Winterfat

What’s blooming: Coral bell, snapdragon and sweet alyssum from seed, chrysanthemum, purple aster.

Inside: Aptenia, geranium; coral honeysuckle putting out new leaves.

Animal sightings: Birds in fruit trees.

Weather: Some very cold mornings; changes in sun angles more obvious; last rain, 29 September.

Weekly update: Winterfat looks the same all year. Most don’t actually notice it. Many, who see it along my drive, tell me it’s chamisa; a few say sagebrush. All that registers is a large, nondescript grey shrub with dark, pealing branches.

When I look more closely, I realize it changes with the seasons and the years. It begins as a small, erect sprig, with clusters of narrow grey leaves covered with white hairs. If it’s not yanked quickly, it puts down a deep tap root that splits into a Y a foot or so below the surface, firmly anchoring it against the winds. It also spreads more fibrous, shallower roots to collect surface moisture.

The little twig becomes several foot long branches rising from a short, yellowish trunk. Each year, new stalks are added, or the existing ones grow longer. My largest shrubs are about 7' wide with spreading 4' long branches, laying over dead wood. In areas where cattle or sheep graze in early winter, mature wood, filled with crude protein, disappears and the vigor of the bush increases from low buds on the trunk.

New leaves appear in spring that nudge off ones that survived the winter. Clusters of young, short, curved leaves are interspersed with inch-long, solitary lances. The rejected leaves join the remains of last year’s seeds in a self-maintained mulch beneath the lowest branches.

Flower spikes emerge in early summer where leaf clusters connect to the branches, an event invisible to all but the most acute observers. Like other members of the goosefoot family, this Chenopodium produces only the most essential parts: male and female organs anchored in separate cups of bracts, protected by tiny horns. No petals, no sepals, no scent.

Once the wind has moved the pollen down stem from the males to the females, across the shrub or to other plants, grey-green seeds form. Their tufts of white hairs transform bushes into piles of fluffy wands spreading above skeletal bases. The shrubs are at they’re most beautiful in early fall when sunlight filters through the seed heads.

Now the weather’s turned cold and the fine hairs that cover the leaves are turning pink. Many seed heads have disappeared, their seeds turned light brown. The branch tips are reverting to their lamb’s quarter form with narrow spikes curving out from clusters of clasping leaves.

Soon they will become forlorn heaps of brittle wood with tiny leaves no longer visible from afar. Beneath the wooly coverings, the leaves of summer were pale green, the twigs straw. In winter, everything looks like a Whistler study in black and grey.

On the ground, still attached seed hairs will collect moisture that will freezes to insulate the embryos from our wide ranging daily temperatures. Then, in the spring, when the air approaches 59 degrees, life will stir itself, new buds swell, and winterfat will rejuvinate itself.

Autumn Leaves

What’s blooming in the area: Áñil del muerto, purple asters.

What’s blooming in my garden: Snapdragon, coral bell bud, petunia behind hollyhock leaves, sweet alyssum from seed, blanket flower, chrysanthemum.

Inside: Aptenia, geranium.

Animal sightings: Quail, ants.

Weather: Some very cold mornings; last rain, 29 September.

Weekly update: We’re having a genuine autumn this year, after several years with no serious frost until late November. After the cold a week ago Monday, trees that had stayed green suddenly were brown. Those that had some intimation of the coming desolation were more intensely yellow. A few had brown, yellow, and green patches.

Beneath the surface, abscisic acid is sealing the joints between branches and leaves, so that no open wounds remain when leaves finally drop. Meanwhile, the rate of photosynthesis is slowing as perennials enter winter dormancy, and the quantity of chlorophyll in leaves is decreasing. As the green fades, other leaf pigments become visible, including the yellow xanthophyll.

Xanthophyll had been known for years when Frederick Addicott’s team reported abscisic acid as a long sought growth inhibiting hormone in 1963. It begins as xanthoxin with 15 carbon, 22 hydrogen, and 3 oxygen atoms which have split from the 40 carbon, 56 hydrogen, and 4 oxygen atoms in a molecule of violaxanthin.

Xanthoxin is inherently unstably, and loses two hydrogen atoms to become abscisic acid aldehyde. When exposed to oxygen, that molecule converts into abscisic acid with a half life of about eight hours and four oxygen atoms. That in turn becomes phaseic acid with another oxygen atom, then dihydrophaseic acid with two more hydrogen atoms.

Xanthophyll sounded much simpler when Jöns Jakob Berzelius described the pigments in fall leaves in 1837. Scientists have since applied the term to any oxygen compound with 40 carbon and 56 hydrogen atoms.

The most important xanthophyll in leaves at dawn is violaxanthin. Instead of shucking off atoms and moving through the plant as abscisic acid, it stays in the leaf and loses an oxygen atom to become antheraxanthin. Later in the day, it loses another oxygen atom to become zeaxanthin, before reverting to its original state in the night.

Scientists want to know more than that zeaxanthin is created to protect the photosynthesis centers in leaves from increased solar energy levels in the day or that abscisic acid is a response to threats from low temperatures and drought. They want to know the nature of the bonds that connect those carbon atoms, the type of oxygen, the enzymes that transform each of the compounds, and the system of communication that triggers the creation of xanthoxin.

I don’t think about molecules, when I look through my windshield at the changing patterns of color formed by groupings of trees against the open fields, the sky, and each other. Still, it’s reassuring to know laboratory scientists remain who use the simple methods we were taught in high school chemistry to submit any scientific postulation, no matter how complex, to the old tests of dissolution, heating, sniffing, and spectrum analysis to reveal the beauty beneath senescent skin.

Virginia Creeper

What’s blooming in the area: Roses, white sweet clover, pink evening primrose, winterfat, chamisa, snakeweed, áñil del muerto, golden and purple asters.

What’s blooming in my garden: Pinks, snapdragon, petunia, chocolate flower, blanket flower, chrysanthemum.

Inside: Aptenia.

Animal sightings: Ants.

Weather: Frost on my windshield Monday morning; last rain, 29 September.

Weekly update: Virginia Creeper. The very name evokes the Blue Ridge or primeval forests that greeted the first settlers at Jamestown.

I shouldn’t be surprised it grows almost elsewhere in the country. After all, many plants are named when they’re first encountered, before more is known about them. Canadians call it Engelman ivy.

Still it’s a surprise to have it constantly volunteering in arid New Mexico. Most of the specimens in the university herbarium are from counties along the Continental Divide, east of the Sangre de Cristo, or along the roads and railroads west from Albuquerque. Nothing from Rio Arriba or its neighboring counties.

The Zhangs and Shi tested Parthenocissus quinquefolia as a potential restoration tool in the Hunshandak sand lands of northern China and discovered that when the woody vine has less soil moisture, it transfers its growth to its taproot and alters the breathing patterns of its leaf stomata.

Here many of the places it grows are shaded, but some are in sun all day. Many, including those under trees, may have access to preserved water. The vines growing along fences may also have found water conserved by nearby roads. The liana is apparently very adept at exploiting soil, water, and light conditions.

Since it seems unlikely it invaded the Española valley by itself, it probably was introduced: the local hardware often sells rooted cuttings. I suspect the plants covering two tall cottonwood stumps down the road were deliberately planted, and I think the vine in front of a large pine tree hitched when they dug the tree up and moved it here.

It has erupted in my yard in so many places I thought maybe the seed was in the soil, waiting for water. But Van Clef and Stiles says that’s not possible, that the seed is only good for a season. Indeed, most forest herbs don’t create seed banks.

The seeds are spread by birds. However, less than half the dozen places it’s growing along the main road are near utility lines. The only vines that aren’t on fences, are in trees. Normally I drive in heavy commuter traffic when the birds have retreated to a few sections of the overhead lines; pigeons prefer the metal roofs of two out buildings. Birds don’t perch everywhere Virginia creeper grows.

In my yard, birds occasionally land on one of the fences, but not the fences where Virginia creeper has attempted to grow. Various types of birds have nested in my porch, in my garage, and in my neighbor’s metal barn. A number of the seedlings have sprouted near the eaves or down wind or downhill from the undereave entry points.
Virginia creeper has been growing next to my neighbor’s barn since at least 1997, but didn’t start to put many vines through or under the border fence until after last summer’s wet season. It usually takes a few years to establish itself. So far, the tendrils haven’t used their adhesive pads to climb the wood, so they might safely be left to compete with the downy chess grass, wild lettuce, and horseweed that grow along that section of driveway.

The only problem with birds as the agent for diffusion is that before there can be seed to drop, there must be flowers. Like other members of the grape family, Virginia creeper’s green floral clusters are so small they wouldn’t be seen from the road and the purple berries are too dark. So it means nothing to say I’ve never seen them blooming. However, Iverson’s team says they don’t flower often, at least in Illinois, and Grey-Wilson warns his vines only fruit during hot summers in Britain.

That leaves a puzzlement. Along the main road, the places with dense colonies of vines are too far apart to be spreading from a single plant, and neither far enough nor close enough for birds. The only alternative is that once a plant is established it roots its own branches, which may grow twenty feet a year, and expands on its own momentum. Then, when it does produce fruit, a bird can move it another thousand feet down the fence or across the road.

It’s persistence and spread may be a bit of a riddle, but nature is unfaed. Most of the year, Virginia creeper blends with other vegetation, dark green leaves in summer, dead leaves in fall, bare branches in winter. For just a brief spell, ended this year by last Monday’s cold, nature shows off when the five-part leaves turn burgundy and reveal their profligacy.

Weather: Windy evenings and cold mornings; last rain, 29 September.

Weekly update: It’s so easy to impute modern life in Rio Arriba county to its Spanish heritage and very difficult to identify the deeper strands of influence without falling into the snares of romanticism or stereotype.

Oñate arrived in our valley in 1598, hunting for gold, and found people who’d been farming along the river confluences for several hundred years. A generation later, Alonso de Benevides saw water for irrigation, piñon for fuel and food, adobe for building, and Spanish settlers on the best lands in 1630.

When Zebulon Pike explored the upper Rio Grande in 1807, he didn’t see enough wood to support a moderate population for 15 years He thought they would be reduced to mudbrick houses and have to settle for "cattle, horses, sheep and goats" rather than crops. He labeled the plains an "internal desert" and people stayed away until artesian wells were introduced.

What separated the two military scouts were the expectations that come with time. Seventeenth century colonists still accepted contact with Spain every three years. Nineteenth century Americans no longer tolerated rivers that weren’t navigable enough to ship crops to market.

The Franciscans saw Tewa speaking pueblos they thought could be turned into farm hands like the Moriscos in southern Spain. Americans met mobile Indians who’d had the horse for many of those intervening 177 years and weren’t about to labor for them.

The natives of arid Spain knew how to live with less than 20" of rain a year, the easterners did not. Landscape and experience influenced how each saw the possibilities of New Mexico.

The expectations of snapdragons are easier to meet. They like cool weather and limestone soil. Mine usually stop blooming in the summer and resume with better flowers in the fall after they’ve grown more leaves. Most years, a few perennials survive the winter to grow, if not bloom, the following summer. Several have gone to seed and reappeared closer to water.

This year the Bells, Sonnets, and Rockets stayed in bloom until August when the monsoons failed, and resumed flowering the middle of September when water returned to the area. When last summer stayed wet and cool, Sonnets and Rockets bloomed until mid-September, then stopped for the year.

Weather is the hidden link to Spain. Back when the earth was covered by jungle in the middle Eocene, 38 to 54 million years ago, a drier area developed outward from the modern Mediterranean. The traditional snapdragon family, Scrophulariaceae, evolved to the west in the Mandran.

When the modern distribution of climates emerged some five million years ago, Antirrhinum developed in the relicts of that Mandran-Tythan band, in modern California and Iberia. The continents had long been separated, so parallel developments could only have resulted from similar genetic responses to changing conditions by species with common ancestors.

My snapdragons may be derived from Spain’s purple Antirrhinum majus that have been bred for color, habit and resistance to fungus, but they aren’t popular here because they came with the conquistadores. The bedding plants are bought as soon as they appear in stores in April because people have had good luck with them and they like the bright complex flower spikes.

An accumulation of experiences has formed both our expectations for a good flower and the snapdragon’s ability to survive our harsh summers. It’s more than wondrous coincidence that both the buyers and the flowers come from Spain, but not an inevitable consequence of shared national heritage. Landscape still matters.

Cutleaf Coneflower

What’s blooming in the area: Roses, silver lace vine, buddleia, datura, Heavenly Blue morning glory, rose of Sharon, narrow leaf globemallow, white sweet clover, chamisa, broom snakeweed, winterfat, Tahokia daisy, Maximilian and native sunflowers, áñil del muerto, ragweed, broom senecio; golden, heath, strapleaf and purple asters; milkweed leaves turning yellow.

Looking south: Rugosa rose, Crimson Rambler morning glory, Sensation cosmos, zinnia
Looking west: Russian sage, catmint, purple ice plant; leadplant leaves turned red, lily leaves turning yellow
Bedding plants: Sweet alyssum, snapdragons, petunia, Dahlberg daisy
Inside: Aptenia, zonal geranium
Animal sightings: Quail, grasshoppers, ants; gopher active; goats in empty field down the road.
Weather: Cold temperatures destroyed grape and zinnia leaves, but zinnias are still blooming; winds continued to scatter seed. Last rain, 9/29/07.
Weekly update: Plants that went into remission in the summer heat and drought are blooming again. The rugosa rose, pinks, and snapdragons do this every year, but it’s not routine for my cutleaf coneflower.
I’m not sure what is normal for it, since it shouldn’t grow here at all. Rudbeckia laciniata prefers stream banks and forest edges, and can’t tolerate drought. My rhizomatous plant must depend on water in the soil rather than atmosphere, since the one is fairly constant here, and the other changes every year.
This particular composite, with its distinctive young green cone, does occur naturally in Rio Arriba county. Standley saw it along the Brazos river north of Tierra Amarilla in 1911. It’s since been spotted along the Rio Vallecitas in Carson National Forest. Both are at much higher elevations than Española.
Even with its seeming obscurity, Curtin found Spanish speakers in northern New Mexico who knew dormilón well enough to tell her they used its leaves to treat gonorrhea and "female trouble" in the late 1940's. More recently, Moore heard it used for late periods as well as uterine and vaginal problems.
The basal rosette of deeply lobed leaves arrived in my yard by chance. I ordered Maximilian sunflowers from an Iowa nursery in 1999, and this was shipped instead. Since it’s not something Henry Field offers, I don’t know if it was a local volunteer, stowed there in some seed, or crowded out a potted plant it bought elsewhere for resale.
My plant normally starts producing clusters of yellow flowers on 5' stalks the end of July and stops five weeks later. Why it’s reblooming now on lower branches when the leaves are already turning yellow is as big a mystery as how it survives this arid environment.
Botanists believe the leaves that produce a plant’s food through photosynthesis control its blooming schedule by sending messages to the cell production center in the central stem when they detect the species specific necessary hours of darkness. That would help explain why the late spring and early summer plants are reblooming, but not this late summer plant.
Perhaps the failure of the monsoons disrupted the cycle of this water loving perennial and stopped the growth of some stems in August. When it finally rained, those inactive stalks may have resumed growth and now are mature enough to send urgent signals to their meristems to convert to reproduction as quickly as possible.
Its taken botanists some seventy years to establish the little they now about flowering cycles. Why should a stray cutleaf coneflower let the most recent theories stop it from blooming when it needs to?

Looking west: Russian sage, catmint, ladybells, purple ice plant.

Bedding plants: Sweet alyssum, snapdragons, petunia, Dahlberg daisy

Inside: Aptenia, zonal geranium

Animal sightings: Quail, ants, bees, grasshopper, flies.

Weather: Rain Monday and Thursday night; windy all day Saturday; ice on my windshield Wednesday morning.
Weekly update: Temperatures fell some mornings this past week, and plants responded. Catalpa, locust, and cottonwood leaves began to yellow. More Virginia creeper turned red. My nasturtium, which had only begun blooming with the rain on the 27th, went dormant again.

Last year the dwarf Jewel bloomed from August 22 to October 20. The large, furrowed seeds were planted the same time both years, the second week in May, but this year’s plants emerged May 25, two weeks before last year’s June 13.

When dates vary so widely, I suspect plants are sensitive to environmental conditions. Garden manuals advise the annuals like cool weather, but assume moisture is available. Since the plants were on the same irrigation regimen both years, the failure of the monsoons in August and the lack of atmospheric moisture must have been critical.

Their ancestral homeland is Perú, but by the time the Spanish arrived, tajsa had spread to south central México where it was eaten. In Perú they used the leaves for recuperative baths and to treat scabs. Nicolas Monardes was the first European to describe flor de la sangre in 1569 when he reported the leaves worked on fresh wounds. We now know the genus contains tropaeolum, a mustard oil that has antiviral, antifungal and antibacterial properties.

Monardes was a physician trained at a time when medical training at Alcalá de Henares still included botany. He worked for Phillip II and had interests in the drug and slave trade in Seville, the primary port for the Americas. He used his contacts to obtain seeds and information from returning sailors.

His seeds probably came from some place on the Caribbean coast, simply because Perú was still serviced by ships that went north to Panama once a year when the prevailing south wind was favorable. Cargo was transshipped across the isthmus. However, his medicinal information more likely came from someone returning from Perú.

Some believe Monardes was discussing Tropaeolum minus, the parent of my Jewel, and others that he was describing Tropaeolum major, the more common vining plant. Many believe the current varieties have resulted from so many crosses, species is no longer relevant, and use major for any nasturtium.

In Perú today, major grows wild on the hills above Ariquipa on the coastal side of the Andes at about 700' where goods from the interior were gathered for shipment to Lima before Cape Horn was discovered in 1616. It has naturalized along the south coast and in inland desert counties of California and currently is expanding its range in the Iberian peninsula, probably as minimum temperatures increase.

Whatever its pleasures where it is colonizing, here, in the rio arriba, nasturtiums survive on the frontier of the possible and respond accordingly.

Weather: Rain Sunday, Friday and yesterday, prairie wet deeper than my shovel; frost on car windows Thursday morning; low hanging, full moon before dark on Wednesday.

Weekly update: We finally got rain last week, and now the habitues of late summer have resumed growing, racing to produce seed before it gets too cold.

The rains began last Monday. Áñil del Muerto germinated last Saturday, and put out its second leaves two days ago. There was sun on Monday and Muhly ring grass showed some green that afternoon, as did the black grama and needle grasses. Downy chess grass sprouted in the drive.

Muhly is one of the grasses that colonizes land denuded by overgrazing. It’s palatable in early spring when it’s growing, but goes dormant in the heat of the summer and turns dry and harsh. When the monsoons appear, it regreens to send up short purple culms with seeds that are also unappetizing.

Not only is it well armed against herbivores, but it also adapts to scarce water. The perennial begins as a small round tuft. Over the years, the tuft turns into an inch or two greyish white wide band that expands outward, leaving an ever widening doughnut opening. When it greens up, it begins on the outer faces, where seeds form. In relatively flat areas, its new growth appears on all sides; on more sloping land ring muhly greens on the downhill or wet side first.

When I see it spread across the top of my south facing slope, I wonder if it prevents or abets erosion by stopping or channeling the flow of water. The recent rains have been able to sink into the ground, instead of rolling downhill. The ring, or its shadow, acts as a small reservoir where other seeds plant themselves and its shallow tenacious, fibrous roots hinder the wind.

The 2" high grass’s life cycle is heavily dependent on rainfall. During the droughts of the past few years, it all but died out, and snakeweed invaded its territory. With last year’s rains, it came back in the area where the needle grass had died, but didn’t try to resettle the area with the broom.

Frederic Clemens believed the order of succession on damaged arid lands was annual grasses, short perennial grasses, bunch grasses with ring muhly, and, finally, the original gramas. Others have since found grasslands rarely get beyond the needle and rice grasses, and that factors like weather and soil influence the progression.

Even if my uphill neighbor hadn’t told me he had worked for the ranch that owned this land before he settled on its perimeter, the mere presence of Muhlenbergia torreyi could have told me. I don’t know if it was cattle or sheep, but the remains of animal chutes near the old road bed don’t look wide enough for full-grown cows.

What I don’t understand is why it only appears on the upward side of my house, and why the lower land and much of the surrounding prairie are predominantly needle grass. I’m guessing there could be differences in the quality of the soil, or that area near the ranch perimeter may have been trampled more and the compacted soils less porous, less receptive to water.

It does appear the grass can’t compete with other vegetation, and that it dies out when either the bunch grasses or the scrub seed themselves. It also doesn’t like being crushed and cracks when it’s stepped on during its dormant phases. It would appear to be the first thing to disappear when humans or animals appear. While it seems common enough, in fact, in this area, its period of existence is limited by both humans and nature.

Weather: At last, some rain on Monday. The storm was severe when I drove through Pojoaque, but the skies were already blue when I got to my turnoff. Water still stood in gullies by the road, and water was flowing in the arroyos I crossed. The road was drying when I started up the rise to my house, but when I got to my drive, water was standing in tire tracks and I could hear the big arroyo running in back. The sun was shining, and a rainbow appeared to the north. When I walked out, even the ground in the bone dry prairie was soft enough to sink into. Storms remained in the area the rest of the week, releasing more water on Thursday and preventing evaporation the other days.

Weekly update: Larkspur is usually described as a hardy, cool season annual. That turns out to be a useful guideline for planting and planning, but doesn’t much explain why I have problems growing it.

Sunset’s garden manual suggests cool season annuals like cool soil and mild temperatures, but doesn’t hazard ideal temperatures. Stokes advises greenhouse owners to prechill larkspur seeds, plant them in soil 45-50 degrees and grow seedlings at 50-54 degreesConsolida, while HPS informs the same growers the optimal germination temperature is 60 degrees and the best growing temperature is 50 degrees.

Seymour told readers hardy plants were those that could be started outdoors, as distinct from a greenhouse or cold frame, and still have enough days to flower. However, he didn’t indicate the number of days required for larkspur, but did recommend planting in May for blooms all summer.

The reason writers may be hesitant to specify the number of days to bloom is that germination times vary from 8 to 15 days for Ann Reilly to a month for June Huston. Peter Loewer had success in 20 days with flowers 100 days after he planted seeds.

Larkspur apparently has not lost its evolutionary sensitivity to climate. Consolida ambigua née Delphinium ajacis are members of the buttercup family, one of the first flowering groups to emerge in the cretaceous age, after North America had separated from Eurasia and temperatures were dropping following the extinction of the dinosaurs some 50 million years ago. As climates continued to change, Ranunculaceae retreated north. Consolida apparently developed in southern Europe, probably in the cooler, mountainous regions of eastern Balkan places like Albania, Bulgaria, and Croatia, and Mediterranean islands like Crete.

Larkspur found its natural environment so favorable, it developed no adaptation strategy for bad years. The seed is only viable for one cycle, which means it must drop and bury itself, then hope winter snow melt fosters it. Wildseed claims 80% of its Rocket Larkspur will germinate; Stokes found its rate was between 74% and 76% in January. Viability declines rapidly after that.

Hot, dry New Mexico is obviously the wrong place for larkspur. I had no success until last year when I dropped Rosalie and Exquisite Rose seeds between perennials in the windy bed shaded by the retaining wall. The seeds I planted last May 20 bloomed from August 30 until killed by frost in late November. This year, I planted seed May 12 that put out its first flower August 29.

My two French grown tetraploids are the only varieties that have prospered here and probably only one of them is, in fact, blooming. I suspect, on the flimsiest of evidence, that it’s the Exquisite because I failed with Rosalie in 1999 and the other was being developed when seedsmen were still creating new offerings by multiple crosses with both Consolida ambigua and possibly other larkspurs. Paeonut found Exquisite Pink in a 1929 catalog.

Sometime, some person somewhere introduced some genetic factor that allows the one cultivar of a winter hungry wildflower to germinate in New Mexico’s late spring, then endure the summer heat to bloom when conditions change in late summer. Here, it turns out, cool season can mean either late spring or early fall.

Weather: Another week of promises, but no lasting rain; last wet ground, September 2, last real rain, August 8.

Weekly update: A week or so ago, The New York Times reported yet more genetic problems have evolved from this area’s isolation between Oñate’s entrada and the advent of the national labs. This time it was drooping eyelids caused by oculopharyngeal muscular dystrophy, probably inherited from a wandering French Canadian trapper, and headaches or seizures caused by cavernous angioma.

Our wild sunflowers blooming everywhere right now can also develop genetic idiosyncracies in isolation. All the flowers along the road and filling fields are a uniform, bright yellow. In my yard, many are darker gold, and a few are motley mixes. The difference is the feral plants mate with one another, while I throw down some purchased seed each year.

These two tendencies, the development of isolated populations and the openness to interbreeding have been instrumental in the development of the sunflower as a commercial crop. The cultivated large seed, single stalk plant diverged from the multiple branched one more than 4000 years ago in North America to become a separate subspecies, macrocarpus.

The Spanish took seeds back to Madrid where they spread through Europe. Peter I introduced them to Russia from Holland, and men like Andrey Bolotov, estate manager to Catherine I in the 1700's, found ways to extract oil. A century later, Russian Mammoth was developed, then exported back to the United States in 1893.

Agribusiness only became interested in hybrids when Americans became concerned about saturated fats, cholesterol, and heart problems, but their model for seed development required plants that did not exist. With corn, they removed the male tassels and fertilized the plants with other pollen. They often used pollen from the original plant to reintroduce fertility into the next generation. The composite disks of sunflowers, with both male and female organs, were too small to manipulate.

In 1969, Patrice Leclercq found a species of sunflower, Helianthus petiolaris, with naturally sterile cytoplasm that would combine with annuus. Soon after, Harry Kinman found the gene to restore fertility. Agricultural suppliers began improving farmer’s seed, and geneticists began testing the inherent dangers of that single prairie sunflower father.

Sunflowers for ordinary gardeners remained untouched. In 1987, when Yasuo Gato bought Vincent Van Gogh’s Still Life: Vase with Fifteen Sunflowers, Thompson and Morgan offered a smaller range of varieties than it had in 1955: one seed plant, Russian Giant, instead of four; one species, Italian White, in place of six; one semi-double, Piccolo; one dwarf, Sahin’s Teddy Bear, one branched sunflower with multicolored flowers, Ernst Benary’s Autumn Beauty, and one with yellow flowers, Sunburst.

People who couldn’t afford $400,000 for a painting and couldn’t summer in Provence, suddenly aspired to the life of Van Gogh and opted for sunflower arrangements. Only things hadn’t change since he rushed to finish work each day by noon before his flowers wilted.

Companies scrambled to produce seeds for the cut flower industry. For them, male sterility meant more than the possibility of a commercial hybrid. It meant little or no pollen to soil table cloths or annoy allergic guests, it meant no heavy oil bearing seeds to bend stems, it meant flowers that had no reason to die.

A number of new branching plants were offered in 1991, but the magic words "little pollen" and F1 did not appear in an American retail catalog until 1994 when Park offered Sakata’s Sunbeam. From the next year on, at least three new varieties have appeared a year as breeders have worked to shorten time to flowering, make them grow in any season, have more disciplined stems, longer vase lives, and more varied colors.

Here in the valley, we don’t think of cutting the flowers; we know them, and their bees, too well from the drive. Instead, we eat them. At least four people this year are growing the traditional Russian plant, but only one other person has colored sunflowers. Meantime, inexorably, the laws of genetics are working each time two pure natives cross-pollinate with the chance some recessive genetic equivalent to drooping eyelid will take hold and spread through the ditches and roadsides.
