Allium jepsonii is a species of wild onion known by the common name Jepson's onion, honoring renowned California botanist Willis Linn Jepson.[2][3][4][5]

Distribution and habitat

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]
