It is native to western North America, where it grows in the Pacific Coast Ranges from southwestern British Columbia to northern California.[2][5][4]


In North America from southern British Columbia south to northern California, west of the Cascade Range to the Coast Range and Siskiyous.[6] It grows at low elevations in open meadows and in mixed woodlands.


Erythronium oregonum is wildflower growing from a bulb 3 to 5 centimeters wide and produces basal, lance-shaped green leaves up to 22 centimeters long and often mottled with brown and white. Thin naked stalks up to about 40 centimeters in height each bear one to three flowers.

Each flower has white tepals with yellow bases, sometimes streaked with dull red. The flower is often nodding, facing the ground. Its tepals are recurved so their points face upward. The stamens and stigma are white and the anthers may be white to yellow.


"John Burroughs is said to have named this species 'fawn lily' because he thought the two leaves looked like the pricked ears of a fawn. more likely, 'fawn' alludes to the mottled leaf coloring."[7]
