(Psophocarpus tetragonolobus) This is one of the most unique beans; it produces delicious pods with four winged edges, the leaves are cooked like spinach and the roots have a delicious, nutty flavor. This high-protein bean is an excellent crop and is so useful in the kitchen. The plants are tropical and do best in warm areas. They will not produce well when the days are long, so it may not yield until fall. Soak seeds 24 hours before planting. We have had a hard time keeping any winged beans on the shelf ever since Mother Earth News ran an article on this bean. Limited quantities.

A diverse group of many relatives of the common bean, they are to be grown like the common bean except as noted: sow beans 1-2 inches deep in full sun, when danger of frost is past. Soaking for 1-2 hours before planting speeds germination. Beans will rot if soil is cold or very wet. Sow bush types 6-12 inches apart in beds.
