Coreopsis Atkinsoniana grows in the following 9 states:Arizona, Georgia, Idaho, Montana, New Mexico, Oregon, California, North Dakota, Washington
It often grows in disturbed areas such as roadsides and cultivated fields.Plains coreopsis, garden tickseed,golden tickseed, or calliopsis, Coreopsis tinctoria, is an annual forb. The plant is common to Canada (from Quebec to British Columbia), Northeast Mexico (Coahuila, Nuevo Len, Tamaulipas), and much of the United States, especially the Great Plains and Southern states where it is often called "calliopsis." The species is also widely cultivated in and naturalized in China.
Growing quickly, Coreopsis tinctoria plants attain heights of 12 to 40 inches (30-100cm). Leaves are pinnately-divided, glabrous and tending to thin at the top of the plant where numerous 1- to 1.5-inch (2.5-to 4-cm) flower heads sit atop slender stems.
Flower heads are brilliant yellow with maroon or brown disc florets of various sizes. Flowering typically occurs in mid-summer. The small, slender seeds germinate in fall (overwintering as a low rosette) or early spring.
The Zuni people use the blossoms of the tinctoria variety to make a mahogany red dye for yarn. This variety was formerly used to make a hot beverage until the introduction of coffee by traders. Women also use a infusion of whole plant of this variety, except for the root if they desire female babies.
Plains coreopsis is cultivated as an ornamental plant for gardens, and as a native plant for wildlife gardens and natural landscaping. It grows well in many types of soil, but seems to prefer sandy or well-drained soils. Although somewhat drought-tolerant, naturally growing plants are usually found in areas with regular rainfall. Preferring full sun, it will also grow in partial shade.
Because of its easy growing habits and the bright, showy flowers of cultivars such as 'Roulettte' (tiger stripes of gold on a deep mahogany ground), plains coreopsis is increasingly used for landscape beautification and in flower gardens.
