'''''Lupinus arboreus''''' ('''Yellow Bush Lupine''') is a species of [[lupin]]e native to the western [[United States]] in [[California]], where it is widely distributed [[coast]]al scrub and [[sand]] [[dune]]s. 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, California|San Luis Obispo County]].

It is a perennial [[shrub]] growing to 2 m tall (hence the alternative common name, '''tree lupine''') in sheltered situations, but more typically 1-1.5 m tall. It has green to gray-green palmate leaves, with 5-12 leaflets per leaf. The leaflets are 2-6 cm long, often sparsely covered with fine silky hairs. Both yellow and lilac to purple flowering forms are known; however, the yellow form is more common, except in the north of the species' range. It is capable of tolerating temperatures down to -12°C and living for up to seven years.
