Local Mexican Hat

Tulip leaves turning brown and seed pods opening.

Looking north: Golden spur columbine, hartweig evening primrose, butterfly weed, squash, chocolate flower, coreopsis, blanket flower, anthemis, Mexican hat, chrysanthemum.

Bedding plants: Petunia, nicotiana, moss rose, snapdragons.

What’s blooming inside: Zonal geraniums, aptenia.

Animal sightings: Hummingbirds, small brown birds, geckos, hummingbird moth, cabbage butterflies, ladybugs, bees, hornets, harvester and small black ants.

Weekly update: Growing wildflowers has always seemed a dubious proposition, if not an outright oxymoron.

When you consider you only trade with reputable suppliers that means you support people who do not gather their seeds or plants from the wild, but use seed or cuttings from plants they’ve perpetuated from ones they or others collected in a sustainable manner.

What little I know of genetics means the nucleus of their stock is probably atypical because it survived being transferred from its natural habitat. Even if the growers had done no selecting for the best flowers or most vigorous plants, nature would have.

When I see black-eyed Susans try to take over my front garden, the idea that émigrés from the eastern United States can do so well leaves me a bit queasy. I can see when they germinate along side improved versions of themselves, that they still look like their wild ancestors, but I can’t say my Rudbeckia hirta are still true wildflowers.


I’ve always been a bit more comfortable with the status of my Mexican hats. Ratibida columnifera, after all, is native to the plains, prairies and mountains below 8300' from Saskatchewan to Chihuahua. Local people have tested it and learned it’s not edible. Keres speakers rubbed the crushed leaves on a woman’s breast to wean an infant. Zuñi curing fraternities used what they tactfully call bile vomit (ya’konakia) as an emetic.


However, I’ve never actually seen Mexican hats growing in the wild. When I’ve seen them blooming along a shoulder I’ve suspected they either had escaped from someone’s garden or been planted by someone taking to heart Ladybird Johnson’s admonishment to beautify. Still, Elmer Wooton and Paul Standley say they’re found in the Santa Fe mountains.

Then, last summer, I saw something that looked like a more feral version growing near the wild asparagus on the farm road. The cones were shorter and fatter, the disc cruder, the red petals smaller, the plants bushier - just the sort of differences one would expect between a true wildflower and its cultivated cousin.


These, however, turn out to be another species, Ratibida tagetes, sometimes called green Mexican hats because they send up a number of stems from their taproots with leaves closer to those of marigolds. It has a smaller range, limited to the southwest, and is part of the diet of a rare form of Chihuahuan grasshopper.

It’s also more useful. Keres speakers considered it strong medicine and used it to treat epileptic fits. They also took it when they went hunting to handle other forms of “craziness.”

The Ramah Navajo, who used common Mexican hat for colds and to treat sheep who were “out of their minds,” used the more localized species as a Life Chant lotion for stomach aches, fevers, birth injuries and sexual infections.

Even Spanish speakers used the ground dry roots in water for lung congestion and to treat female trouble. Leonora Curtin, who found it growing at 8000' at Truches, says people used the same term, dormilón, for this and for cut leaf coneflower. They used the second for gonorrhea and menstrual problems.

The implied relationship between Rudbeckia laciniata and Ratibida was explored in 1935 by Ward McClintic Sharp. He believed Rudbeckia’s center of diffusion was on the Ozark-Appalachian plateau where many plants had sought refuge during the glaciers, and that Ratibida was an offspring that moved into the new geological formations when conditions permitted, abetted by its unique seed dispersal methods.

More recently, Lowell Urbatsch and others have discovered DNA doesn’t support a mother-daughter relationship, but a sisterhood instead. The genetics do suggest the local Mexican hat, which has 32 chromosomes, is older than the common one with 28.

The local Mexican hat is still growing wild by the asparagus this year while the common ones were evicted from my garden years ago after they became too aggressive and proved they could survive quite nicely in the native grasses.

The black-eyed Susans are going to be expelled as soon as they establish themselves where I don’t have to handle their spiny wooden stems when I clean the front bed in spring. So far, they’ve objected, choosing other, choicer spots around the house instead. They’ve proven themselves independent if not wild.
