Lupinus perennis, commonly known as Wild Lupine, is a striking native perennial found in sandy prairies, open woodlands, and savannas of Illinois. It thrives in well-drained, nutrient-poor soils and full sun.
This legume produces tall spikes of vibrant blue to purple pea-like flowers in late spring, attracting bees, butterflies, and hummingbirds. It is the host plant for the endangered Karner blue butterfly and plays a crucial role in nitrogen fixation, improving soil health.
For Illinois native plant lovers, Lupinus perennis is a beautiful and ecologically valuable addition to prairie gardens, pollinator habitats, and restoration projects.
