Erigeron scopulinus is a North American species of flowering plant in the family Asteraceae known by the common names rock fleabane[1] and Winn Falls fleabane.[2] It has been found in the southwestern United States primarily in Arizona and New Mexico with a few isolated populations in Colorado.[3]
Erigeron scopulinus grows in on ledges and in cracks in cliffs in the mountains. It is an perennial, mat-forming herb rarely more than 3.5 cm (1.4 inches) tall, forming a thin taproot and spreading by means of underground rhizomes. The inflorescence generally contains only one flower head. Each head contains 10–20 ray florets surrounding many yellow disc florets.[1][4]
