Erigeron cronquistii grows on ledges, cracks in cliff faces, and erosion pockets at high elevations in the mountains. It is a very small perennial herb rarely more than 7 cm (2.8 inches) tall, forming a taproot and sending up many shoots so that it forms a dense clump of stems. Each stem generally produces 1 or 2 flower heads, each head with 10-25 white or pale pink ray florets plus numerous yellow disc florets.[3]
