Tarwi (Lupinus mutabilis)
Tarwi is a lupine bean native to the Andes. Like most Andean plants, it performs best in cool weather. It is very drought resistant, but yields much better with consistent water. One of the easier beans to grow in the cool coastal parts of the Pacific Northwest. Tarwi requires soaking in water for several days before it is edible. This leaches out alkaloids that make it bitter.
