Allium jepsonii is endemic to the foothills of the Sierra Nevada foothills of California, in Tuolumne, Placer, El Dorado, and Butte Counties. It is found at elevations of 300–600 metres (980–1,970 ft) and grows on clay soils.[6]

Description

Allium jepsonii, the Jepson's onion, grows to a height between about 20 and 40 centimeters from one or two oval-shaped bulbs. There is a single cylindrical leaf which is about the same length as the stem.

The inflorescence holds 20 to 60 small flowers, each under a centimeter long with pink-veined white tepals with curling tips.[4][6][7]
