Perennials.  Sap is milky white.  Colony-forming from stolons and creeping rhizomes.  Stems are scapose, densely covered with a variety of hairs, including  minute, stellate (branched) hairs; long, bulbous-based bristles and stalked glands.  Typical height is 6 to 15 inches.

Inflorescences consist of compact clusters of a few flower heads on short peduncles located at the tops of stems.

Flower heads are ligulate.  All florets are bisexual and fertile.  Corollas are bright orange-red, turning magenta-purple with age.  Involucres are 6-8 mm high.  Involucral bracts are densely covered with black, stalked glands and long, spreading bristles.

Basal leaves (persistent throughout much of the season) are oblanceolate to obovate, borne on winged petioles, and covered with both long, spreading hairs and minute, stellate hairs.  Stem leaves are few, much smaller than basal leaves, often nearly inconspicuous.

Plants of fields, lawns and open, disturbed ground.  Flowers May to June, and sometimes a second time in Autumn.  Not native.
