Meet Common Broad-leaf Lupine

Did you know that the Lupine’s Latin name, lupus, means wolf? This is because it was once believed that the plant ‘wolfed up’ all of the soil’s nutrients, rendering it infertile. However, the Common Broad-leaf Lupine actually enriches the soil, playing a vital role in maintaining its health.

Wild Lupine is the only food for the larvae of the Karner Blue butterfly, which is found in the Midwest and Eastern United States. The butterfly larvae crawl up the stems of wild lupines to feed on the new leaves. Habitat loss for lupines has also affected the butterfly. The Karner Blue is nearly extinct over much of its range and is now designated as “federally endangered.”

Next time you see a Lupine, stay long enough to notice what insects come to visit it. What insects rely on Lupines where you live?
