Ecology & Life History
General Description: Prairie Aster has stems that are 1-7 dm high and clustered on a woody-thickened, branched rootcrown. The narrowly lance-shaped leaves near the base of the plant have entire margins and are petiolate and up to 20 cm long, while those on the upper stem are shorter, strap-shaped, and lacking petioles. Foliage is glabrous to slightly roughened. The 3-60 flower heads are borne in an open, flat-topped inflorescence. The glabrous, overlapping involucral bracts of each head are 5-7 mm long, each with a greenish apex and a prominent, thickened midrib. The 10-25 rayflowers are white and 5-9 mm long, and the numerous disk flowers are white. The achene is glabrous and has a pappus of bristles that are thickened toward the top.
Diagnostic Characteristics: This species differs from other SOLIDAGO in having white flowers, resembling an ASTER. It can be distinguished from the latter by its flat-topped inflorescence, its thickened, involucral bracts that are often blunt at the tips, and the thickened pappus bristles.
