A somewhat hairy perennial, the leafless flowering stems usually growing singly from a rhizome, reaching 10-30 cm in height. Leaves form a basal rosette with no cauline leaves. The blades are 2-5 cm long, narrowly rhombic to rhombic-ovate, narrowed gradually to short, broad petioles. Prominent marginal hairs line the leaves and are rusty-woolly on the lower surface.

The inflorescence is a short, compact panicle, subtended by a leafy, rusty-woolly bracts. The calyx is broadly conic, the 5 lobes oblong-lanceolate, 1-2 mm. long and reflexed. Individual flowers have 5 white, obovate petals, 1.5-3 mm. long, at least half as broad as long. Stamens number 10 and are short, awl-shaped.[1]

Bloom Period

Late March - July[1]


West side of the Cascades, British Columbia to Lincoln County, Oregon, and in the Columbia River Gorge[1]


Prairies, grassy slopes and vernally moist areas, sea level to subalpine[1]


used ornamentally in rock gardens


Can be propagated by seed, division or cuttings.
Seed should be planted in winter and barely covered. Germination takes place in 1 to 3 months at 16-21°C
Division should be done after flowering.
