Its common names are Woodland tickseed, showy tickseed, and beautiful tickseed. Coreopsis pulchra is native only to the Cumberland Plateau of northeastern Alabama (and perhaps historically in nearby Georgia)[2] where it grows on sandstone outcrops. Because of its narrow habitat requirements and small geographic range, this species is considered imperiled. Coreopsis pulchra blooms from June through September, and the flower heads are gold with dark centers. It is a perennial, herbaceous plant that grows to a height of about 60 cm (2 feet).[3]References1. ^{{Cite web | publisher =NatureServe | title = Coreopsis pulchra | url = http://explorer.natureserve.org/servlet/NatureServe?searchName=Coreopsis+pulchra | accessdate = 2014-07-13}} {{Taxonbar|from=Q5170288}}{{Heliantheae-stub}}2. ^Biota of North America Program 2014 county distribution map 3. ^Flora of North America Coreopsis pulchra F.
