Perennials.  Tuft-forming or rhizomatous.  Stems may be either glabrous or somewhat pubescent, but not glaucous.  Typical height is from 2 to 4 feet.

Flower heads are radiate, quite numerous, crowded on branches in an inflorescence that is often taller than broad, and often pyramidal in shape.  Rays are pale blue-violet to nearly white.  Disc floret corollas are very pale yellow, turning pink/magenta with age.  Involucral bracts are glabrous, well-appressed, not spreading.  Dark green zones are often diamond-shaped and tinged with purple.

Basal and lowermost stem leaves are usually deciduous by flowering.  Most leaves below the inflorescence are heart-shaped, conspicuously toothed and borne on a narrow, winged petiole.  Leaves are flat (not wavy margined).

Plants of mesic woods, open woods, clearings and roadsides, usually with at least partial shade.  Flowers September to mid-October.  Native.
