Lupinus saxosus is a species of lupine known by the common name rock lupine. It is native to eastern Washington, eastern Oregon, and the northeast corner of California,[1]where it grows in sagebrush and other habitat. It may also be native to Idaho and Nevada.[2]
Description
[edit]This is a perennial herb growing erect 20 to 30 centimeters (7.9 to 11.8 in) tall. Each palmate leaf is made up of 7 to 13 hairy leaflets 1 to 4 centimeters (0.39 to 1.57 in) long. Stiff long hairs are found on the undersides and edges of the leaves, with no hair on top. The inflorescence is a dense raceme of many flowers sometimes arranged in whorls. The flower is between 1 and 2 centimeters (0.39 and 0.79 in) long and blue in color with a yellowish or violet patch on its banner. The fruit is a shaggy-haired legume pod up to 4 centimeters (1.6 in) in length. The flowering time is early spring.[1] The 8 to 12 leaflets have acute or rounded tips. It is shorter than most lupine species.[3] The bloom period is between the months of May and June. You shouldn’t eat any part of the lupine.[4] It is most commonly found between the elevations of 4,000 to 6,000 feet (1,200 to 1,800 m).[5] 52.3% of the time it was found, it was found in May, and 19.8% of the time, it was found in June. [6][7]
Habitat
[edit]This lupine grows in poor rocky soils and is often found in shallow soils that are dry to basalt bedrock by midsummer.[7]
