Blooming in early to midsummer, they are borne atop silvery-haired stems, just above the foliage. They are attractive to butterflies, hummingbirds and many pollinators. The blossoms are followed by hairy legume pods containing several beanlike seeds. Blanketing desert flats, mountain slopes, and meadows across the Southwest, Silvery Lupine looks breathtaking when planted in mass.
