description Lupine Overview

Lupines (Lupinus) are a genus of over 200 flowering plants in the legume family, Fabaceae, native to the Americas and the Mediterranean region. They are easily recognized by their tall, erect spikes of densely packed pea-like flowers and their palmately divided leaves. As legumes, they form a symbiotic relationship with soil bacteria, allowing them to fix atmospheric nitrogen. Historically, several Mediterranean species have been cultivated for thousands of years for their edible seeds, known as lupini beans.
