Summary
Foothill death camas is a western United States native monocot perennial herb growing from a tunicated bulb with a dark brown to black coat; a glabrous stem 20–70 cm tall rises above basal linear leaves 20–50 cm long and 6–16 mm wide, with cauline leaves sheathing and much reduced upward. An open panicle 10–30 cm long bears white to cream flowers with six tepals and a yellowish-green gland at the base; most flowers are bisexual, with some staminate, and pedicels 3–25 mm.
In cultivation, it prefers dry, well-drained habitats such as sagebrush scrub and conifer forests; it can naturalize and is Hardy in USDA zones 3b–9b; ornamental use is possible in well-drained soils tolerant of dry conditions. All parts are poisonous if ingested, bulbs especially toxic; traditional uses include crushed bulbs in poultices by Shoshone, Paiute, and Washoe.
