Summary

Naked mariposa lily is a bulbous perennial herb native to California and Oregon, with a short, usually unbranched stem 10–25 cm tall and a persistent basal leaf 5–15 cm long. The inflorescence bears one to several erect, bell-shaped flowers with a white to pale lavender perianth; sepals 10–12 mm, petals 14–16 mm, glabrous and without cilia. The fruit is a capsule about 2 cm long, and flowering occurs May–July in moist grassy areas, lake and bog margins at elevations 1200–2500 m.

In cultivation, it prefers sun to partial shade with very low water and should not be irrigated once established. It naturally grows in moist meadows, lake margins, and wetland-riparian and forest plant communities; has an edible bulb used by Indigenous peoples.
