Weekly update: Mail order companies like to send free samples, although the last successful product promotion was the Delicious apple in 1895.
Wildseed Farms, of Fredericksburg, Texas, sends a seed mix, which I dutifully plant, usually with no results. The exception was 2012 when some plains coreopsis sprouted under a leaky hose connection. That wasn’t where I planted the seed. I assume it washed down the hose line.
I bought some seeds the next year and planted them in the same place. Only a few germinated. I tried again last year in a different location. Nothing. This year, with all the late spring rain, last year’s seed not only germinated, but the flowers have varied in coloring.
Coreopsis tinctoria was identified by Thomas Nuttall in 1819 in Arkansas Territory. The fibrous roots grow along the Missouri and both sides of the Mississippi south of their confluence near Saint Louis. In New Mexico, Augustus Fendler saw the yellow and mahogany notched flowers east of the Mora river, "between Coon Creek and Pawnee Fork in shallow hollows in the prairies, said to have been made by the buffaloes in wallowing."
Buffalos did roll, but wallows tended to be natural depressions that collected water and were enlarged by the animals. No doubt their shaggy coats collected seeds, which could have been deposited along the waterways west of the Mississippi.
Plains coreopsis also appears in clusters of contiguous counties that are separated from one another. One rather suspects seeds were purchased, and when found useful were passed from gardener to gardener.
Nuttall told members of the National Academy of Sciences in Philadelphia that "it promises to become the favorite of every garden where it is introduced." He also mentioned it produced a yellow dye. By mid-century, Joseph Breck called it a "a well-known hardy annual." In 1851 the Bostonian offered two varieties, one an ornamental, the other listed as Dyeing Calliopsis.
In New Mexico, Paul Standley discovered the composite near Shiprock on the Navajo reserve early in the twentieth century. Matilda Coxe Stevenson said, "this plant was introduced among the Zuñi many years go by the Navajo for making into a beverage." The Ramah Navajo were using a cold infusion to treat infections caused by lightning, especially enlarged abdomens, in the early 1950s.
Both groups incorporated it into their ritual lives. Navajo administered it during the Waterway Chant, a subgroup within the Shooting chants. Among the Zuñi, it was "drunk by women desiring girl babies." The Zuñi also used kia’naitu flowers with other florets to dye yarn a deep red.
The flowers are delicate when they bob over the tops of over plants. It’s not surprising the seeds spread to Europe and Japan. In China it’s grown as a cut flower and has naturalized in moist sandy or clay soils.
What is surprising is that it reached the Uyghur living in the far northwest Kunlun mountains. They used it in a tea to treat high blood pressure and diarrhea. Chinese scientist have tested the plant and discovered the link was the red pigments that made it a natural antioxidant.
