Erigeron philadelphicus L.
Philadelphia Fleabane, Fleabane Daisy
Asteraceae (Aster Family)
USDA Symbol: erph
USDA Native Status: L48 (N), CAN (N)
The fleabane daisy grows along roadsides and in fields and woodlands. It has more than 150 threadlike, white ray flowers. The center, disc flowers are 5-toothed and yellow, and there are many flower heads to each much-branched stem. The yellow center with the large number of very fine ray flowers is the best identification. They are much finer than those of other daisies or asters. Flower heads are 1/2-3/4 inch across.
The geneus name, from Greek eri ("early") and geron ("old man"), presumably refers to the fact that the plant flowers early and has a hoary down suggesting an old man's beard. Robin's Plaintain (E. pulchellus) is slightly shorter and has fewer, but larger, lilac or violet flower heads, as well as stem leaves that are sparse and stalkless but do not clasp the stem; it is insect-pollinated and also spreads actively by runners.
