Lupinus arboreus
Also called Tree Lupin, Tree Lupine, Bush Lupine, Coastal Bush Lupine
Yellow bush lupine is an evergreen shrub from coastal California and northern Baja, grown for its fragrant yellow pea-like flowers and its use in stabilising sand dunes. Give it full sun and very well-drained soil, and it will thrive with little water.
Lupinus arboreus, the yellow bush lupine, coastal bush lupine (US) or tree lupin (UK), is a species of flowering plant in the legume family Fabaceae.
The yellow-flowering form of Lupinus arboreus is widely grown as an ornamental plant, for its attractive flowers in traditional, native plant, and wildlife gardens. It is also used to bind drifting sand dunes. It can be seen growing in cracks in vertical stone walls, due to the sharp drainage. Lupins can also be cultivated on balconies or patios in pots.
It has gained the Royal Horticultural Society's Award of Garden Merit.
The shrub is indigenous to California, US, where it is widely distributed among coastal sage scrub and sand dunes. Because it has been widely introduced in the state, 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.
