A wide-ranging species of eastern North America, though rare in New England and now extinct in Maine. New Hampshire still has a wild population of this lupine.
In June, lavender-blue flower spires with charming, radiating leaves make this an excellent landscape and garden plant for hot, dry well-drained infertile soil (will not grow in moist soil). Like most legumes, it improves soil fertility through nitrogen fixation. This wildflower is the sole host plant for the rare Karner blue butterfly. Deer-proof.
