Erigeron compositus - photos and description

Saskatchewan's Wildflowers

Low tufted growth habit. Early flowering, beginning early May. Flowers with white ray florets and yellow disks, flower heads to 1 cm in diameter. Many flowers with only a few white ray florets. Scapes leafless, pubescent, the plants we observed had scapes rising to 4 cm tall. Foliage densely pubescent, grey green in colour. Leaves twice divided into 3 linear leaflets. Leaves to 9 mm long including petiole, entire leaf to 8 mm wide.

Uncommon, listed as an S3 by the Saskatchewan Conservation Data Centre. Habitat is hillsides, badlands, gravelly ridges on Saskatchewan's southern prairie.

Height is listed in Budd's Flora from 2 to 15 cm.

This plant might be confused with another low-growing, early flowering Fleabane, Erigeron radicatus. However that plant's basal leaves are not dissected into 2 or 3 lobes.
