Wing beans are only known to be cultivated, no wild specimen has ever been found. Original cultivation began in Papua New Guinea where the greatest diversity of varieties exist. Wing beans thrive in tropical climates with warm weather, humidity and abundant rainfall. They are grown in Southeast Asia, specifically areas within both the Phillipines and Thailand. Wing beans also grow prolifically in tropical Africa and within the islands of Hawaii. Almost every part of this unique plant is tasty and edible including the flowers, tubers, pods, and beans. The fresh young pods of the winged bean are similar to green beans with a chewy texture and a slightly sweet taste.
