Lupinus lepidus, the Pacific lupine, prairie lupine or dwarf lupine is a perennial herbaceous plant in the pea family (Fabaceae) native to western North America.
Lupinus lepidus is a small hairy perennial that reaches NaNabbr=offNaNabbr=off.[1] Palmately compound leaves extend up the stem, but most are basal.[1] The inflorescence is a dense spike-like raceme, with pink, purple, or blue flowers that often have a yellowish spot.[1] The plant blooms from mid-April through August, depending on elevation and habitat.[2] The fruit is a pod containing multiple seeds.[1]
Many varieties have been described, several of which are considered separate species by some authorities.[3]
The species is endemic to western North America,[4] where it may be found in open areas from low prairie, open montane forest, to the alpine. Although rare in British Columbia, its range extends south from Alaska to southern California and eastward to the Rocky Mountains.[5] In California, it is mainly a species of meadows and areas that are moist during the spring growing season in the Sierra Nevada mountain range, from 4900to.
