1 packet (50 seeds) - Winged Bean - Dau Rong - Four Angled bean - Manila bean Winged bean is also known as Asparagus pea, Winged pea, Four Angled bean, Manila bean, Princess bean, and Dragon bean. Almost every part of this tropical plant is edible: The beans (used as a vegetable), the leaves (cooked like spinach), the roots (similar to potato), and the dried seeds (used for flour). Cultivation: Prepare fertile, well-drained soil in a warm, sunny location. Seeds can be difficult to germinate. For better germination, pre-sprout seeds indoors by soaking in water for 24 hours until swollen and then keep at 77F until sprouted. Scarify seed coat for seeds not swollen and resoak. Plant when seeds sprout. Keep soil moist. Fertilize sparingly. Train to grow on a vertical support. Large vigorous vines can reach 9-12'. Harvest beans up to 3" in length.
