Part of the pea family, this vibrant purple bloom has a recognizably lupine shape, with clusters of flowers forming a narrow, tapering bloom. Arroyo lupine is native to California and does well in a number of habitats, including the chaparral habitat found in the Irvine Ranch Natural Landmarks, and is more water-tolerant than other lupine family members. It is one of the more than 50 species grown at Irvine Ranch Conservancy’s Native Seed Farm, where it is used along with other native plants for restoration projects. Lupines are attractive to pollinators like bees, birds and butterflies. Arroyo lupine’s water tolerance and appeal to pollinators makes it a great choice for a home garden.
