A slender-stemmed herb 1 to 3 feet high, softly pubescent, perennial by stolons and offsets. Stem and midrib on the under surfaces of the leaves densely downy-pubescent. Basal and lower stem leaves spatulate or obovate, dentate, 1 to 3 inches long, blunt at the apex, narrowed at the base into short petioles; upper stem leaves cordate-clasping and smaller. Heads of flowers one-half to 1 inch broad, in a corymbose panicle, borne on slender peduncles thickened at the summit. Each head with one hundred to one hundred and fifty ray flowers, one-sixth to one-third of an inch long, fringelike, light rose-purple to pinkish in color, surrounding a yellow center of disk flowers. Involucres of the heads depressed-hemispheric, composed of narrow, linear bracts, pubescent and with dry, membranaceous margins. Buds drooping, but flowers borne erect.
The Poor-Robin's-plantain (Erigeron pu1chellus) resembles this species but is not as tall and has smaller heads with shorter ray flowers.
