San jacinto lupine
Lupinus hyacinthinus
San Jacinto lupine is a striking native perennial from California's mountains, producing tall spikes of vivid blue-violet flowers beloved by pollinators. It prefers well-drained, slightly acidic soils in partial shade to full sun, and like other lupines, it fixes nitrogen in the soil, benefiting neighboring plants. Avoid overwatering and heavy clay soils, as root rot can be an issue in poorly drained conditions.
