Snake bean

Snake Bean (also known as Yardlong bean, Asparagus bean, or Chinese long bean) is a plant species in the legume family, scientifically known as Vigna unguiculata subsp. sesquipedalis. It is a subspecies of the cowpea, grown specifically for its strikingly long edible pods. The plant is native to Southeast Asia and is widely cultivated in warm regions around the world.

Description

The Snake Bean plant is a climbing annual vine which grows by means of twining around supports. The plant produces yellow or white flowers, followed by the long, slender pods. The pods, which can reach lengths of up to 90 cm (35 in), are typically harvested while still immature, before they become fibrous and tough. The beans inside the pods are small and undeveloped, with the pod itself being the main part of the plant that is eaten.

Cultivation

Snake Beans are a warm-season crop and are typically grown in tropical and subtropical regions. They prefer full sun and well-drained soil. The seeds are sown directly into the soil after the last frost, and the plants require a trellis or other support to climb on. Snake Beans are relatively fast-growing, with the pods typically ready to harvest within 60 to 70 days of planting.

Culinary Uses

Snake Beans are a common ingredient in many Asian cuisines, particularly those of China, Thailand, and the Philippines. They can be eaten raw in salads, but are more commonly cooked. They can be stir-fried, steamed, or boiled, and are often used in dishes such as pad thai and adobo. The flavor of Snake Beans is similar to that of green beans, although they have a slightly more intense, nutty flavor.

Nutritional Value

Snake Beans are a good source of protein, vitamin C, vitamin A, and dietary fiber. They also contain significant amounts of iron, calcium, and potassium.
