Plants of dry to mesic woods or clearings.  An early flowering period occurs in June, and may be followed during Autumn by a second flowering.  Native..

Perennial. Stems are solitary or few from a woody caudex. Fibrous-rooted.  Stolons are not produced.  Stems are scapose, glabrous and often glaucous, bearing at most 1 or 2 very small, scale-like leaves.  Typical height is 1 to 2.5 feet.

Inflorescences are open, with a few to several, ascending branches, and a small number of flower heads per branch.  Peduncles are moderately long.  Branches and peduncles are usually sparsely covered with minute stalked, glandular hairs.

Flower heads are ligulate, with 15-40 florets per head.  All florets are bisexual and fertile.  Corollas are bright yellow.  Involucres are  7-9(-10) mm high, sparsely covered with minute, black, stalked glandular hairs.

Basal leaves (typically present at flowering) are obovate to broadly elliptic, with long, spreading hairs along the margins (and elsewhere), and with prominent purple veins.  Upper leaf surfaces are glaucous.  Lower leaf surfaces are sometimes purple tinged.
