(Vigna unguiculata subsp. sesquipedalis) is a legume cultivated for its edible green pods containing immature seeds. Despite the common name of “yardlong”, the pods are actually only about half a yard long, so the subspecies name sesquipedalis is a more accurate approximation. These never grow in cold climates and require hot climate for growth. The soil must be well drained, fertile and the texture which is suitable is loamy. The pH of soil should be 5.5-7.5.
