Erythronium montanum
Also called Avalanche lily, Glacier Fawn Lily, Western White Fawn Lily, White Glacier Lily
Erythronium montanum is a bulbous spring wildflower of the lily family, native to mountain meadows and woodlands of the Pacific Northwest, known for its white flowers that bloom as snow melts. It is rarely grown in gardens and is best kept cool and moist in the growing season with a summer dormancy.
Erythronium montanum, the avalanche lily or white avalanche lily, is a member of the lily family native to coastal British Columbia and the alpine and subalpine Olympic and Cascade Ranges of the Pacific Northwest of Washington and Oregon.
Erythronium montanum flowers shortly after the snow melts in late spring, in damp subalpine woodlands and alpine meadows, often in extensive patches. Blooming plants may persist into midsummer about the edges of snowfields. In the central Cascades, it is often found flowering admixed with Clintonia uniflora and Trillium ovatum at the lower elevation end of its range, and with Pulsatilla occidentalis(syn. Anemone occidentalis) at higher elevations. Distinguishing characteristics of this species are the oblong-lanceolate unmottled leaves and tepals that are white with a yellow base.
