About Succulent Lupine (Lupinus succulentus) Lupinus succulentus is a species of lupine known by the common names hollowleaf annual lupine, arroyo lupine, and succulent lupine. It is native to California, where it is common throughout much of the state, and adjacent sections of Arizona and Baja California. It is known from many types of habitat and it can colonize disturbed areas. The amount of fertility and moisture generally dictates the height of the plant.
