Common names include stiff tickseed, wedgeleaf coreopsis, prairie coreopsis, prairie tickseed, and finger coreopsis.
Coreopsis palmata is a perennial herb reaching about 80 centimeters (32 inches) in height. The leaf blades are often lobed, but are not divided into leaflets as in some related species. The flower heads contain ray florets up to 2.5 centimeters long, or sometimes longer. They are yellow, and generally a paler shade of yellow than related native Coreopsis.
