Erigeron radicatus

Low plant with almost all leaves in a basal cluster. Leaves are linear, we measured one at 34 mm long and 2 mm wide. Flower heads solitary, white petals with yellow disk florets, flower heads measured at 1 cm in diameter. One or two stem leaves. Plant pubescent. Begins flowering late May.

Height listed in Budd's Flora to 10 cm, we measured scapes to 8 cm tall.

Habitat is slopes and crests of eroded hills on southern prairies. Rare, listed as an S2 by the Saskatchewan Conservation Data Centre.

This plant might be confused with another low-growing, early flowering Fleabane, Erigeron compositus. However that plant's basal leaves are dissected into 2 or 3 lobes.

Photos taken May 31st, on a steep clay hill near Rockglen, about 200 km southwest of our home in Regina, SK.
