Growing White Lupine in your area

White lupine (Lupinus albus) produces high-protein seeds (40% protein) and is an excellent soil builder with aggressive taproots. Sow in early spring (cool-season crop). 1" deep, 4-6" apart in rows 18-24". Important: raw lupine seeds contain bitter alkaloids that are toxic—they MUST be debittered through extensive soaking and boiling before consumption. Sweet (low-alkaloid) varieties exist but are less common. Lupine fixes significant nitrogen. Beautiful white/pale blue flowers. Primarily grown as a cover crop and green manure in WV.

Cultural History

Lupines have been cultivated for food for at least 3,000 years in the Mediterranean. Ancient Romans and Egyptians ate lupine beans after extensive processing to remove bitter alkaloids. The Andean lupine (L. mutabilis, chocho) was a staple food of Inca civilization. Modern 'sweet lupine' varieties with low alkaloid content were developed in Germany in the 1920s, making lupine food-safe without extensive processing. Lupine protein is increasingly used as a plant-based protein alternative.
