Description
This species is a perennial herb growing from rhizomes with a fibrous root system. It has an erect stem reaching about 90 centimetres (35 inches) in maximum height.[4] The leaves are alternately arranged, and most are near the base of the stem. The blades have lobes subdivided into toothed segments. They are hairy to woolly, especially on the undersides. The blades are up to 35 cm (14 in) long and are borne on petioles up to 30 cm long. Blooming from May to July, the flower heads are in arrays or clusters, 1.5–2 cm (5⁄8–3⁄4 in) long apiece, with equally long bracts.[4] They contain up to 50 long yellow or orange disc florets and no ray florets. The fruit is a veiny cylindrical cypsela with a long pappus of many barbed, white bristles.[6][7]
Distribution and habitat
It is distributed from southern British Columbia to northern California,[6] along both the Cascades and northern Coast Ranges.[4] The plant grows in oak and pine forests and meadows, sometimes on serpentine soils.[7]
