Erigeron clokeyi is native to the sage scrub of Nevada and far eastern California, and it can also be found in the talus of the eastern flank of Sierra Nevada.[1] There are a few additional populations reported from Beaver County in Utah.[2]
Erigeron clokeyiis a small perennial herb with leaves mostly around the base of the plant. The hairy, unbranching erect stems each hold an inflorescence of a single flower head which is about a centimeter (0.4 inches) wide. The head has a center of golden yellow disc florets and a fringe of sometimes as many as 55 very light to medium purple (occasionally white or pink) ray florets which are usually reflexed (bent away from the center).[3]
