Lupinus luteus
B tier
Lupinus luteus is yellow lupin—smaller yellow seeds historically important as feed and green manure, with emerging food uses where sweet lines are debittered or bred low-alkaloid. Flavour is beany and slightly more assertive than premium white lupini snacks. Less common as pickled bar beans than albus but appears in flour and protein ingredients. Confirm food-grade sweet status before culinary use. Species fixes nitrogen aggressively in rotation systems that later supply food crops.
