The '''yardlong bean''' is also known as the long-podded cowpea, asparagus bean, snake bean, or Chinese long bean. It is known as ''dau gok'' in [[Cantonese (linguistics)|Cantonese]], ''thua fak yao'' in [[Thai language|Thai]] and ''kacang panjang'' in [[Malay language|Malay]], and ''vali'' or ''eeril'' in [[Goa]], [[India]]. Despite the 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 and is only distantly related to the [[common bean]]. It is a vigorous climbing [[annual plant|annual]] [[vine]]. A variety of the [[cowpea]] family, it is grown primarily for its strikingly long (35-75 cm) immature pods and has uses very similar to that of a [[green bean]]. The pods, which begin to form just 60 days after sowing, hang in pairs. They are best if picked for vegetable use before they reach full maturity. The plant is subtropical/tropical and most widely grown in the warmer parts of Southeastern Asia, Thailand, and Southern China. Yardlong beans are quick-growing and daily checking/harvesting is often a necessity. The many varieties of yardlong beans are usually distinguished by the different colors of their mature seeds.

The crisp, tender pods are eaten both fresh and cooked. They are at their best when young and slender. They are sometimes cut into short sections for cooking uses. They are used in [[stirfrying|stirfries]] in [[Chinese cuisine|Chinese]]. In [[Malaysian cuisine]] they are often stirfried with [[chile pepper|chillies]] and [[shrimp paste]] (''[[sambal]]'') or used in cooked salads (''kerabu'').
