Lupinus luteus is known as annual yellow-lupin or European yellow lupine. It is native to the Mediterranean region of Southern Europe. It occurs on mild sandy and volcanic soils in mining belts. As a wild plant, it is widespread over the coastal area in the western part of the Iberian Peninsula, Morocco, Tunisia, and Algeria, on the islands of Corsica, Sardinia and Sicily and in Southern Italy. It is most likely that in Israel and Lebanon it has turned wild. Cultivated in Northern Europe and the CIS (Belarus and Ukraine) as well as, on a smaller scale, in Western Australia and South Africa. Having previously been cultivated in southern France and on Madeira, it has turned wild there. Using combinations of such characters as the colour of the corolla, the carina’s edge, vegetative organs and seeds, 18 varieties, 4 subvarieties and 6 forms have been identified. The plant's yellow seeds, known as lupin beans, were once a common food of the Mediterranean basin and Latin America. Today they are primarily eaten as a pickled snack food.
