Green beans (American English), also known as French beans and Runner beans (British English), are the unripe fruit of any kind of bean, including the yardlong bean, the hyacinth bean, the winged bean, and especially the common bean (Phaseolus vulgaris), whose pods are also usually called string beans in the northeastern United States, but can also be called snap beans.
Food features:Green bean varieties have been bred especially for the fleshiness, flavor, or sweetness of their pods. Haricots verts, French for "green beans," may refer to a longer, thinner type of green bean than the typical, American green bean.
Place of origin:The first "stringless" bean was bred in 1894 by Calvin Keeney, called the "father of the stringless bean," while working in Le Roy, New York.
Dietotherapy function:Green beans are often steamed, boiled, stir-fried, or baked in casseroles. A dish with green beans popular throughout the United States, particularly at Thanksgiving, is green bean casserole, which consists of green beans, cream of mushroom soup, and french fried onions.
