Green beans, also known as string bean, snap bean in the northeastern and western United States, or ejotes in Mexico, are the unripe fruit of various cultivars of the common bean (Phaseolus vulgaris). Green bean cultivars have been selected especially for the fleshiness, flavor, or sweetness of their pods.
Haricots verts, French for "green beans", also known as French beans, French green beans, French filet beans, Fine beans (British English), is a variety of green bean that is longer, thinner, crisp, and tender. It is different from the haricot bean, which is a dry bean.

Green beans are of nearly universal distribution. They are marketed canned, frozen, and fresh. 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.
Some restaurants in the USA serve green beans that are battered and fried, and Japanese restaurants in the United States frequently serve green bean tempura. Green beans are also sold dried and fried with vegetables such as carrots, corn, and peas.
Green beans are found in two major groups, bush beans and pole beans.
Bush beans are short plants, growing to approximately two feet in height, without requiring supports. They generally reach maturity and produce all of their fruit in a relatively short period of time, then cease to produce. Gardeners may grow more than one crop of bush beans in a season.
Pole beans have a climbing habit and produce a twisting vine. Runner beans have a similar habit but are a different species of bean.
Over 130 varieties of green bean are known. Varieties specialized for use as green beans, selected for the succulence and flavor of their pods, are the ones usually grown in the home vegetable garden, and many varieties exist. Pod color can be green, purple, red, or streaked. Shapes range from thin "fillet" types to wide "romano" types and more common types in between.
Many but not all bean pods contain a string, a hard fibrous spine running the length of the pod. This is often removed before cooking, or may be made edible by cutting the pod into short segments. 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.
