The "ball" part of the flowers is a white wooly mass with many spines thus forming attractive pedestals for the several rose-purple flowers. The blooming period is from late spring to late summer. Leaves to 10 in (25.4 cm) long. Height: 2-5 ft (0.6-1.5 m).
Low to high elevations mostly west of the Cascades.
An attractive plant of alpine meadows, the plump roots are about 1 in (2.5 cm) long and can be boiled and eaten.
