Sesquipedalis (Asparagus Bean)

The asparagus bean is a legume cultivated for its edible green pods containing immature seeds, like the green bean. It is also known as the yardlong bean, long-podded cowpea, Chinese long bean, bodi/bora, snake bean, or pea bean.

Linn. Asparagus bean. French Yard- Long. Taukok. Fig. 194. Long rambling or twining annual plant, with deltoid ovate or deltoid-oblong blunt -pointed leaflets: fis. rather large, 1-3 in the axils, the peduncles elongating and bearing the pods at their sum mits: pods compressed or nearly terete, slender and very long (often 2ft.) and sometimes curiously twisted; seeds small, ob-long, more or less truncate or squared at the ends, usually reddish or dim-colored.


The pods, which can begin to form just 60 days (2.0 months) after sowing, hang in groups of two or more. They are used as vegetable when they are picked before they reach full maturity; however, overlooked mature pods can be used like dry beans. When harvesting, it is important not to pick the buds which are above the beans, since the plant will set many more beans in the future on the same stem.

The plants take longer to reach maturity than bush beans, but once they start producing, the pods are quick-growing and daily checking and harvesting is often a necessity. The plants can produce beans until the first frost. The plant attracts many pollinators, specifically various types of yellowjackets and ants.


They are a good source of protein, vitamin A, thiamin, riboflavin, iron, phosphorus, and potassium, and a very good source for vitamin C, folate, magnesium, and manganese.
