In addition to the spectacular cardoon, Nancy has some special and interesting plants that will be appearing in this plot later this spring. Since these plants are primarily from tropical and subtropical areas of Asia, most will not be planted until well after our last scheduled frost here in North Texas. Among these plants will be Winged beans. The winged bean (Psophocarpus tetragonolobus), also known as cigarillos, goa bean, four-angled bean, four-cornered bean, manila bean, princess bean, asparagus pea, and dragon bean, is a tropical herbaceous legume plant.
