Lupinus arboreus (Yellow Bush Lupine) is a species of lupine native to the western United States in California, where it is widely distributed coastal scrub and sand dunes. Because it has been widely introduced, there is some uncertainty about its native range; it is thought to be native from Point Reyes National Seashore south to San Luis Obispo County.
