White Mariposa Lily (Calochortus eurycarpus) is often found in masses, standing proud among the grasses and herbs of mountain meadows, grasslands, and open forests throughout the intermountain west.
A member of the lily family, white mariposa lily grows from a perennial bulb with a single grass-like stem up to 20 inches tall bearing 1-5 flowers. The flower features three large white petals each with a prominent purple blotch in the center. Near the base of each petal a small, yellow, crescent-shaped gland attracts beetles by secreting a nectar-like substance.
