Long Beans

Vigna unguiculata subsp. sesquipedalis is a legume cultivated to be eaten as green pods. It is known as the yardlong bean,[1] bora, long-podded cowpea, asparagus bean,[1] pea bean,[1] snake bean, or Chinese long bean.[1] Despite the common name, the pods are actually only about half a yard long; the subspecies name sesquipedalis (one-and-a-half-foot-long) is a rather exact approximation of the pods' length.
This plant is of a different genus than the common bean. It is a vigorous climbing annual vine. The plant is subtropical/tropical and most widely grown in the warmer parts of South Asia, Southeast Asia, and southern China. A variety of the cowpea, it is grown primarily for its strikingly long (35-75 cm) immature pods and has uses very similar to that of the green bean. The many varieties of yardlong beans are usually distinguished by the different colors of their mature seeds. -Wikipedia
