BEAN ‘Red Winged’ Vegetable Seeds
Common name: Winged Bean
Scientific name: Psophocarpus tetragonolobus
Family: Fabaceae
Winged bean is a perennial, vigorous tropical climber growing to 3 – 4 m with mauve-blue flowers and four-angled pods with wavy margins. The pods, leaves, flowers, and tubers are all edible. It is high in protein: the seeds contain 34% protein and 17% oil, while the root contains 20% protein. The young leaves (top three sets of leaflets on a shoot) are cooked and eaten. The flowers taste like sweetish mushrooms. It is among the world’s most effective nitrogen-fixers.
In a 100-gram portion of cooked winged beans, there is a protein content of 10.6 g.
