Lupinus nanus, the sky lupine, field lupine, dwarf lupin, ocean-blue lupine[1] or Douglas' annual lupine, is a species of lupine native to the western United States. It is found natively in California, Nevada, and on Steens Mountain in eastern Oregon. It tends to grow on slopes[2] and in open or disturbed areas below 1300 meters.[3]
It grows 6 to 20 inches (15 to 51 cm) tall with blue flowers containing white or yellow spots. It is an annual plant that blooms in the months of March, April and May.[4]
It contains anagyrine[5] and is considered toxic if directly ingested.[6] Among the biologically active chemicals found in the plant are genistein, 2'-hydroxygenistein, luteone and wighteone.[7]
