Munz's Onion (Allium munzii)

Munz's onion is a bulb-forming perennial herb endemic to western Riverside County, California, and occurs primarily in areas between the elevations of 1,200 to 2,700 feet from Temescal Canyon southeast to the foothills of the San Jacinto Mountains. The plants are adapted to seasonal drought and variable annual rainfall, prefer clay soils, and are dormant from mid-summer through autumn. When in bloom, they produce a single leaf and a leafless flower stalk 0.5 to 1.2 feet tall topped with a cluster of 10 - 35 white flowers.
