Arroyo Lupine
Lupinus succulentus
Arroyo Lupine (Lupinus succulentus) is an annual forb native to Western US states (such as California and Arizona) that can thrive in USDA Zones 7–11 as a self-seeding annual. Reaching a mature height of 1–3 feet with a stout, succulent upright growth habit, it features fleshy, palmately compound dark green leaves and produces tall spikes of deep blue to purple pea-like flowers. It thrives in moist to dry loamy or clay soils, washes, and disturbed slopes and is ideal for rapid slope stabilization, roadside revegetation, and soil nitrogen enrichment.
