Wild Perennial Lupine (Lupinus perennis) is a showy native wildflower that blooms in late spring with spikes of blue and bluish-purple flowers. This species prefers sandy soil and full sun. Once established, it will naturalize, attracting bees, birds, butterflies, and hummingbirds.
While most people know about the relationship between monarch butterflies and milkweed, the Karner Blue butterfly has the same kind of relationship with the wild lupine. The Karner Blue was federally listed as endangered in 1992. This butterfly is most widespread in Wisconsin and the state has implemented a Wisconsin Habitat Conservation Plan. Habitat throughout the range of the Karner Blue butterfly has been lost as a result of land development and lack of natural disturbance, such as wildfire and grazing by large mammals. Such disturbance helps maintain the butterfly’s habitat by setting back encroaching forests, encouraging lupine and flowering plant growth. Submitted by Linda Anderson, Certified Master Gardener
