Lupinus perennis

Sundial Wild Lupine

Beautiful blue flowers adorn the plants from spring into summer. The palmate leaf is attractive all year long. Perfect for a dry, sandy site. This lupine enhances soil fertility by fixing atmospheric nitrogen into a useful form. It is pollinated by a wide variety of bees. It is the larval host plant for Karner Blue, Frosted Elfin, Wild Indigo Duskywing, and the Persius Duskywing butterflies and skippers. Deer tend to leave this plant alone.

Native Trivia

Sundial Wild Lupine is in the pea family.  The plant does not need to be fertilized; in fact, it actually adds fertilizer to the soil by fixing atmospheric nitrogen, providing a better growing environment for its fellow meadow dwelling plants.

Sundial Wild Lupine is the only known host plant for the Karner Blue butterfly caterpillar. Habitat loss has led to the decline and put the Karner Blue on the endangered species list.
