Erigeron modestus A. Gray
Plains Fleabane, Prairie Fleabane
Asteraceae (Aster Family)
Synonym(s): Erigeron lobatus var. warnockii, Erigeron plateauensis, Erigeron warnockii
USDA Symbol: ERMO2
At first, this short-lived perennial forms a low, hairy-leaved clump. Numerous white, aster-like flowers are carried above the pubescent foliage on leafless stalks which nod under the weight of the unopened, pink flower buds. Later in the season, the lower leaves wither away and stem leaves appear on the now-branched stalks. By late in the season, the plant has fallen over and taken on a sprawling habit.
