Lupinus, commonly known as lupin or lupine (North America), is a genus of flowering plants in the legume family, Fabaceae. The genus includes over 200 species, with centers of diversity in North and South America. Smaller centers occur in North Africa and the Mediterranean.
The species are mostly herbaceous perennial plants 0.3–1.5 m tall, but some are annual plants and a few are shrubs up to 3 m tall. An exception is the chamis de monte (Lupinus jaimehintoniana) of Oaxaca in Mexico, which is a tree up to 8 m tall. Source
