Woolly sunflower has numerous flower heads, each with a dime-sized yellow central disk surrounded by 8-14 yellow ray flowers. A common plant of drier, often rocky slopes. Flowers from May to August.

Variety lanatum has large heads, with the involucre 9-12 mm in height, and the rays about 1- 2 cm in length. The number of rays ranges from 8- 13. The leaves are entire to pinnatified. This variety ranges from 10- 60 cm tall.
