Erythronium is a genus of spring-flowering perennials, several species of which are native to the area from Northern California to British Columbia. Commonly called fawn lilies, they carry their flowers on slender stems, growing from basal leaves. The flowers come in shades of cream, yellow and pink and generally have pendent, recurved petals. Early spring bloomers, they go dormant in mid to late summer.

Yellow fawn lily or yellow glacier lily, Erythronium grandiflora, grows in alpine or sub-alpine areas, in moist meadows and forest openings and at the edge of glaciers. Its bulbs are eaten by grizzly bear and mule deer graze the foliage. Native Americans often steamed the corms and ate them.

Erythronium revolutum, pink fawn lily, is native to open woods, along streambeds and in damp meadows, from coastal to low elevations. Its corms were also consumed by Native Americans.

White fawn lily, Erythronium oregonum, is found in environments similar to the pink fawn lily, but in lower, mainly coastal areas. The leaves of the white fawn lily are mottled with brown or white blotches.
