Yellow bush lupine is predominantly a dune species, but it can be found along roadsides and in disturbed areas. Flowers appear in May to July in northern California (earlier in the southern part of its range). Yellow bush lupine hybridizes with the native L. littoralis, which is smaller (less than two feet) and more prostrate-decumbent, has purple and white flowers, and always has a hairy upper leaf surface.
Intermediates usually are smaller and more prostrate than L. arboreus, with blended yellow, purple, and white flowers (Wear 1998). In the southern portion of its range yellow bush lupine can be easily distinguished from blue bush lupine (L. chamissonis), which can achieve the same height but has silver, densely hairy leaves that appear gray-blue and light-violet to blue flowers.

Lupinus arboreus, yellow bush lupine (USA) or tree lupin (UK), is a species of flowering plant in the legume family Fabaceae.
The shrub is endemic to California, 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.
從這二份資料中可以看出，這黃色的Lupine可是在加州的海岸線才有機會看得到的！
