The caterpillar food plant of San Francisco's rare and endangered Mission Blue butterfly, Silver Lupine grows 3-4 feet tall with feathery silver foliage and a heavy summer bloom of bright blue blossoms. A proven favorite for low maintenance, wildlife attraction, and unparalleled beauty.
The lupines are a wonderful genus -- drought-tolerant, beautiful, and an important habitat plant for butterflies. Like all members of the legume family, lupines also fix nitrogen in the soil (which naturally fertilizes the other plants growing around them).
