About Coreopsis palmata Nutt.
This species is currently classified as Coreopsis palmata Nutt., and was previously known under the synonym Anacis palmata. It is a perennial herb that grows to approximately 80 centimeters, or 32 inches, tall. Its leaf blades are often lobed, but unlike the leaves of some related species, they are not split into separate leaflets. The flower heads hold yellow ray florets that are up to 2.5 centimeters long, and can sometimes grow longer. These florets are typically a paler shade of yellow than other related native Coreopsis species. The center of each flower head holds many disc florets, which are yellow when they bloom and darken as they dry. Plants flower during summer, and their leafy herbage may turn red as it ages in the fall. This plant is native to central United States and central Canada. Its native range is concentrated mostly in the Mississippi Valley and adjacent areas, stretching from Louisiana north to Manitoba, and east into southwestern Michigan. It grows naturally in habitats including prairie, disturbed prairies, open woods, roadsides, and rocky ridges.
