Erythronium oregonum is a species of flowering plant in the lily family which is known by the common name giant white fawn lily. It is native to western North America from British Columbia to California, where it grows in coastal mountain ranges. This wildflower grows from a bulb 3 to 5 centimeters wide and produces wide 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 petals with yellow bases, sometimes streaked with dull red. The flower often faces the ground with the petals recurved so their points face upward. The stamens and stigma are white and the anthers may be white to yellow.
