Weather: Clouds but no rain, furnace came on yesterday morning; last rain, 8/31/08; 12:40 hours of daylight today.
Weekly update: Fall has come to finish a year when nothing arrived on time. Spring was cool, but the rains stopped in March. Plants that expected water budded but didn’t flower. Some that have great shows for a week or two, instead bloomed sporadically all season. The coral bells are still opening new florets.
The winds were delayed, but once they began in April, they never stopped. Plants that won’t tolerate strong buffeting went dormant. Annual seeds that came up stopped growing, and some, like the larkspur and bachelor buttons, simply disappeared.
When the rains arrived earlier than usual, the first part of July, the winds undid their ablutions. Sunflowers are only now in full bloom, three weeks later than last year. Black-eyed Susans and Mexican hats that usually are little more than ripening seed cones this time of year are still flowering.
Last week morning temperatures started falling into the 40's, and the African marigolds and tall red zinnias that finally had started to bud, may never bloom. The one cheerful iconoclast in this anachronistic mix of flowers and seed heads is the yellow cosmos that usually opens by the first of August. In the morning sun, some weeks later than usual, brilliant spots of orange lurk among the lower stems of summer natives where I dropped narrow brown seeds the end of May.
I discovered this central American composite when I lived in Michigan, where my first attempt with the Bright Lights cultivar in 1986 succeeded. Here it took several years before I realized the seeds would only germinate where my house provides shade from mid-afternoon and shelter from southern and western winds.
Cosmos sulphureus is native to southern México and Guatemala, but has spread as far north as Durango, as far south as Ecuador. Bernardino de Sahagún reported the Aztec were using xochipalli flowers for dye when the Spanish arrived. It came to this country as an ornamental, where it was reported wild in the pine lands west of Silver Palm in Dade County, Florida in 1916.
In its preferred homeland, yellow cosmos can grow into a seven-foot bush that blooms all year, but becomes seasonal when it moves beyond the tropics. To promote the zone 8 perennial as an annual, growers needed to modify its habits to bloom the first year. When Thompson and Morgan introduced the shorter, three foot Orange Flare in 1955, it still warned seed "should be sown early" to flower before frost. Now it takes about two and a half months for my Bright Lights to bloom.
By the 1980's, breeders were looking for shorter plants that could complement the ubiquitous French marigolds in suburban gardens. Thompson and Morgan promoted Sunny Red, bred by Sahin, Zaden, as "the first truly dwarf and compact form" in 1986. My first Bright Lights towered two feet above my California poppies, their bare branches extending like windmill sails. Here the hairy square stems only reach a foot.
When Bodger introduced Bright Lights, it described the introduction with its ragweed style leaves as "a bright mixture of yellow, gold, orange and red shades." Most of my flowers are pumpkin, a few the yellow of squash blossoms. In Oakland County, Michigan, with its different soils and weather, yellow dominated.
In a year when nothing can be forecast except uncertainty, its surprising and just a bit reassuring to have an annual follow its normal schedule, bloom the usual ten weeks from planting, even when the sowing was delayed by bad weather and winds, when drought and unexpected temperatures slowed its growth. Such constancy is the more endearing when I remember how much the same cultivar differs between southern Michigan and northern New Mexico, and how the species transforms itself when it migrates.
