Perennials.  Taprooted.  Stems are green or purple, mostly glabrous, at least below inflorescences.  The sap is milky white.  Typical height is 4 to 6 feet.

Overall inflorescences are panicle-like, narrow or broad, the branches spreading to ascending.  Flower heads are distributed singly or in small, tight clusters in leaf axils or along branches.

Flower heads are ligulate, borne on short peduncles, drooping to spreading in flower.  Florets number 7 to 13 per head, the corollas white or tinged pink.  Involucral bracts are glabrous, in two series, the inner series, green or pink; the outer series green, and much shorter.

The pappus is of minutely barbed bristles, typically deep red-brown (rust-color), rarely yellowish.

Lower stem leaves are often present at flowering.  Leaves are green glabrous on the upper surface, pale and sometimes pubescent on the undersides, varying in shape from broadly ovate or triangular to more narrowly ovate (upper leaves).  Lower to mid-stem leaves are borne on long petioles, and irregularly lobed (sometimes 3-lobed); the two lateral lobes tending to flare outward.

Plants of rich, deciduous forests and woodlands.  Flowers August into mid-September.  Native.
