Lupinus sparsiflorus, Coulter's lupine, is a species in the Fabaceae (Legume) family native to North America. In the United States it occurs in California, Nevada, Arizona and Utah, and in Mexico it is found in Baja California and Sonora. In California it is found from the coast to the dry inland mountains of the southern part of the state. Other common names include Mojave lupine, a name it shares with Lupinus odoratus. This is an annual herb growing 20 to 40 centimeters tall. Each palmate leaf is made up of 7 to 11 very narrow leaflets up to 3 centimeters long and just a few millimeters wide. The flower cluster is a fuzzy spiral of several flowers each around a centimeter long. The flower is blue or purple, becoming darker with age, with a white to pink patch on its banner. There is one reocognized subspecies, ssp. mohavensis, which is found only in the desert or semi-desert areas of Riverside and San Bernardino Counties.
