Lupinus albicaulis is a species of lupine known by the common name sickle-keel lupine. It is native to the western United States from Washington to California, where it grows mostly in mountain habitat. It is a hairy, erect perennial herb often exceeding a meter in height. Each palmate leaf is made up of 5 to 10 leaflets each up to 7 centimeters long. The inflorescence is up to 44 centimeters long, bearing whorls of flowers each 1 to 1.6 centimeters long. The flower is purple to yellowish or whitish in color and has a sickle-shaped keel. The fruit is a silky-hairy legume pod up to 5 centimeters long containing several seeds. In Oregon, where the plant is native, it has been cultivated for several uses, including reforestation and revegetation of roadsides and other disturbed habitat.
