TheYardlong Bean (Vigna unguiculatasubsp.sesquipedalis) is a long, thin Asian bean, also known as the long-podded cowpea, asparagus bean, snake bean, or Chinese long bean.
It can measure from one to three feet in length, but are best eaten when they are 12 to 20 inches long, before they reach full maturity
It is a bean with a mild taste, similar to a Western string bean, that is grown in varieties identified by color as either light (pale) green or dark green beans.
The plant is of a different genus than the common bean. It is grown primarily for its strikingly long (35-75 cm) immature pods and has uses very similar to that of a green bean.
It is a vigorous climbing annual vine. The plant is subtropical/tropical and most widely grown in the warmer parts of Southeastern Asia, Thailand, and Southern China.
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.
The crisp, tender pods are eaten both fresh and cooked. They are at their best when young and slender. Use before they reach full maturity.
French beans are tender, slender beans with green, rounded pods, 4 to 6 inches (10 to 15 cm) long. French beans are smaller than common green beans and have a soft, velvety pod.
The pods are eaten whole, including the immature seeds, when they are still young, juicy and tender.
Quite fleshy for their size, only tiny seeds inhabit these delicate pods. They have a delicate texture and sweet flavor.
French beans generally grow as a bush, which grows twelve to twenty inches tall depending upon the variety you decide to grow. However there are some varieties that climb similar to runner beans, these varieties grow up to seven foot tall.
There are three commonly known types of green beans: string or runner beans, string less or French beans (depending on whether the pod has a tough, fibrous "string" running along its length), and snap beans, with a thin flat pod that requires less cooking time.
French Beans are one of the most commonly eaten green beans in India. Most Indian households make French beans as a dry vegetable either with cubed potatoes or without them.
French beans contain phosphorus, vitamins A, B, D and starch, much iron, which aid blood cells production.
Vitamin B in them benefits the spleen and kidneys.
They help to alleviate swelling stomach, bad appetite, premature ejaculation, and frequent urination.
French beans are neutral in nature and can be consumed frequently.
TheGuar ki Phalli or Cluster Bean(Cyamopsis tetragonolobus) is an annual legume and the source of guar gum.
It grows best under conditions with frequent rainfall, but tolerates arid conditions well.
About80% of world production occurs in India.
Young, fresh cluster beans have a narrow and long body with tiny pods. They are harvested for vegetable use.
From the mature pods the seeds are harvested to be dried and powdered to flour known asguar gum. Guar gum is used as thickening agent in commercial food preparations like ice creams and as a stabilizer in cheese and cold-meat processing.etc.
Cluster Beans are not only low in calories but are also very effective in lowering the blood sugar and cholesterol levels.
