Discussion | This species occurs in the Coast Ranges of southern British Columbia, and disjunctly to southern Vancouver Island, the Olympic Peninsula, and Cascade Mountains from Mount Rainier National Park in Washington to central Oregon.

Erythronium albidum often forms extensive colonies in which nonflowering, 1-leaved plants far outnumber flowering, 2-leaved ones. It is very widespread in eastern North America, more common in the central states than E. americanum and often occurs in slightly drier sites.
