Erigeron philadelphicus; Asteraceae (aster family)
Isn’t this just too perky for words?
There are several hundred species of Erigeron worldwide. Three or four* of them can be found in this area, and should be blooming within the coming month. I’ve found what I believe to be robin-plantain (Erigeron pulchellus) in bud already. The plant pictured above stands about 2 1/2 feet tall; the flowers occur in loose terminal clusters, mostly.
*depending which authority you consult; there’s a lot of mix-up with common and botanical names
