Perennials.  Colony-forming from rhizomes.  Stems are flexuous, densely pubescent.  Typical height is 24 to 30 inches.

Inflorescences are open, flat- to round-topped, with spreading to ascending branches; each main branch with only a few flower heads.

Flower heads are radiate, nodding in bud.  Ray florets are pistillate and fertile,  white to faintly bluish.  Disc florets are bisexual and fertile, yellow, turning reddish with age.  Involucral bracts are of unequal size, appressed, lacking a distinct, apical green zone (though some chlorphyll may be present).

Basal leaves are deciduous by flowering.  Stem leaves are alternate, elliptic/obovate, coarsely toothed, tapering to long, slender tips.  Leaves of immature plants and early-season leaves may appear whorled due to short stem internodes.  The largest leaves are at mid-stem, those above and below mid-stem becoming smaller.

Cypselae are obconic and densely gland-dotted.  The pappus is of 3 series of minutely-barbed bristles, the outermost series much shorter than the inner series.

Plants of rich, mesic to damp forests; swamps; also common in mountains up to 4,000+ feet.  Flowers August into early September.  Native.
