Allium jepsonii

Allium jepsonii (Ownbey & Aase ex Traub) S.S.Denison & McNeal is a Californian species that grows in the Sierra Nevada foothills in two different areas, one on serpentine in the north and the other on volcanic soils in the central foothills. It has a single, terete, rat-tail-like leaf, from which pops out a flower stem from a basal incision near the base, and a small head of white, lightly nerved flowers in July. Needs excellent drainage. The stems tend to recline, as shown in the image. The species is often found on serpentine. For a while it was listed as an endangered species and has now been delisted due to discoveries of new populations.
