Sky Lupine
Lupinus nanus

Fragrant spikes of blue-and-white pea flowers carpet California coastal hillsides and open valleys in spring over palmate, silky-haired foliage. A fast-growing native annual that fixes nitrogen on dry slopes, attracting bees and blue butterfly larvae before setting seed and vanishing by summer.
