Lupinus succulentus, also called Arroyo Lupine, Hollowleaf Lupine, or Succulent Lupine, is native to the Southwestern United States. Its native range includes coastal and central California, and into Arizona and Baja California. They can be found along grassy slopes and are adaptable to a wide range of soil conditions. The soil fertility and moisture available to the plant will affects its mature size. The common name, Arroyo, translates to "canyon" in Spanish, names for the habitat where this species is often found growing. Arroyo Lupines are perfect to pair with California Poppies and native grasses. They are deep rooted and can be used for erosion control.

Arroyo Lupine is also a host plant for the endangered Mission Blue butterfly, as well as West Coast Lady, Painted Lady, Gray Hairstreak, Orange Sulphur, Silvery Blue, and Acmon Blue butterflies. When the caterpillars eat the leaves, you may see holes or transparent areas in the leaves, but don’t worry – you’ve successfully created butterfly habitat!
