Lupinus cruckshankii Hook
Lupinus mutabilis is a species of lupin grown in the Andes, mainly for its edible bean. Vernacular names include tarwi (tarhui), chocho, altramuz, Andean lupin, South American lupin, Peruvian field lupin, and pearl lupin. Its nutrient-rich seeds are high in protein, as well as a good source for cooking oil. However, their bitter taste has made L. mutabilis relatively unknown outside the Andes, though modern technology makes it easier to remove the bitter alkaloids. Like other species of lupin beans, it is expanding in use as a plant-based protein source.
