Leaves of lupinus andersonii grow mostly along the stems, not at the base of the plant. They are palmately divided into relatively wide leaflets (six to nine), with hairy surfaces and edges. Leaf stalks are about the same length as the longest leaflet, around 2.3 inches. Stems grow upwards, and are also hairy.
Flowers are formed on the upper part (up to nine inches) of the stem, in an elongated cluster, and they are colored variously white, pale yellow or pale purple. The center spot on the banner petal is white, later purple. All petals are hairless. The light green seed pods are hairy, and about 1.5 inches long. Plants inhabit dry regions of California, west Nevada and southwest Oregon, at medium to high elevations.
