Erigeron sivinskii is a North American species of flowering plant in the daisy family known by the common name Sivinski’s fleabane..[1] It has been found in the southwestern United States, in the States of Arizona and New Mexico.[2][3]

The species is named for botanist and forester Robert C. Sevinski.[4]

Erigeron sivinskii grows on red clay and shale slopes in desert scrub and open pinyon-juniper woodland. It is a small perennial herb rarely more than 8 cm (3.2 inches) tall. The inflorescence generally contains only one flower heads per stem. Each head contains 21–33 ray florets each ray white with a lilac stripe down the middle. These surround many yellow disc florets.[1][4]
