Green bean Information
Green beans are the unripe, young fruit and protective pods of various cultivars of the common bean ( Phaseolus vulgaris).   Immature or young pods of the runner bean ( Phaseolus coccineus), yardlong bean ( Vigna unguiculata subsp. sesquipedalis), and hyacinth bean ( Lablab purpureus) are used in a similar way.  Green beans are known by many common names, including French beans,  string beans (for old varieties; modern varieties are stringless),  snap beans,  snaps,   and the French name French: haricots vert.
They are distinguished from the many other varieties of beans in that green beans are harvested and consumed with their enclosing pods, before the bean seeds inside have fully matured. An analogous practice is the harvest and consumption of unripened pea pods, as is done with snow peas or sugar snap peas.
Historically, green bean pods contained a string, a hard fibrous strand running the length of one side of the pod. This string was either removed before cooking, or made swallowable by cutting the pod into short segments. Modern, commercially grown green bean varieties are stringless and lack strings, though heirloom varieties may retain this trait.

Green beans are eaten around the world, and are sold fresh, canned, and frozen. They can be eaten raw or steamed, boiled, stir-fried, or baked. They are commonly cooked in other dishes such as soups, stews and casseroles.
A dish with green beans popular throughout the US, particularly at Thanksgiving, is green bean casserole, a dish of green beans, cream of mushroom soup, and French-fried onions.  Some US restaurants serve green beans that are battered and fried, such as green bean tempura. Green beans are also sold dried, and/or fried with vegetables such as carrots, corn, and peas, as vegetable chips.
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.  Most modern green bean varieties do not have strings. 
- Bush beans are short plants, growing to not more than 2 feet (61 cm) in height, often without requiring supports. They generally reach maturity and produce all of their fruit in a relatively short period of time, then cease to produce. Owing to this concentrated production and ease of mechanized harvesting, bush-type beans are those most often grown on commercial farms. Bush green beans are usually cultivars of the common bean (Phaseolus vulgaris).
- Pole beans have a climbing habit and produce a twisting vine, which must be supported by "poles", trellises, or other means. Pole beans may be common beans (Phaseolus vulgaris), runner beans (Phaseolus coccineus) or yardlong beans (Vigna unguiculata subsp. sesquipedalis).  
Over 130 varieties (cultivars) 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.[ further explanation needed] Yellow-podded green beans are also known as wax beans.
