Daisy Fleabane or Lesser Daisy Fleabane, Erigeron strigosus
Asteraceae or Sunflower Family
 

Erect daisy-like plant of summer.  Flower heads about 1/2 to 3/4 inches wide, with 50 to 100 white to pinkish ray flowers, and many yellow disc flowers in the centers.  Stem leaves mostly are untoothed and do not clasp the stem.  Stem hairs lie close to the stem.

A native preferring open areas.  Common along trails and the Riverway, and in the butterfly meadows.

Fleabanes are easily recognized by their daisy-like flowers with a large number of very narrow rays.  Robin's plantain (E. pulchellus) has somewhat larger flowers, usually pink to blue or violet, but sometimes white, and most of its leaves are basal.  It blooms in the spring.  Common fleabane (E.  philadephicus) also blooms in the spring, and its leaves clasp the stem.  Annual fleabane (confusingly, also called daisy fleabane) (E. annuus) blooms in the summer along with this species.  Its leaves are toothed, and its stem hairs stick out.  Oxeye daisy (Chrysanthemum leucanthemum) also blooms in the summer, but has fewer, wider rays.
