Description:

Sundial Lupine features blue, pea-like flowers on elongated stems that bloom April-July. Attractive, dark green, compound-palmate leaves orient themselves to the sun. This wildlife-friendly perennial is a valuable nectar and pollen source for hummingbirds and native bees. Its dried seeds are enjoyed by birds. Sundial Lupine is a host plant to butterfly and moth larvae (caterpillars), including Frosted Elfin (Callophrys irus), Elf (Microtia elva), Wild Indigo Duskywing (Erynnis baptisiae), and Persius Duskywing (Erynnis persius). Sundial Lupine is the only known host for larvae of the Karner Blue butterfly (Lycaeides melissa sub. samuelis), which is nearly extinct over much of its range. Plant Sundial Lupine in perennial borders, meadows, edges of woodlands, and in sandy, naturalized areas of your yard that offer full sun. They are susceptible to powdery mildew.
