Lupinus perennis
Common Name: Wild Lupine
Wild Lupine is a perennial legume that grows 1 to 2 feet tall, featuring palmately divided leaves and striking blue to purple pea-like flowers arranged in vertical spikes. This species thrives in dry, sandy soils and is commonly found in oak savannas, open woodlands, and prairies. Wild Lupine is a key host plant for the endangered Karner Blue Butterfly, making it an important species for pollinator conservation. In landscapes, it is ideal for naturalized gardens, native plantings, and restoration projects where sandy, well-drained soils are present.
