Green Beans

While green beans are typically referred to as string beans, many varieties no longer actually feature the fibrous 'string' that runs down the length of the earlier varieties. Green beans are also commonly known as snap beans. Haricots verts are French green beans that are very thin and very tender.

Green beans are in the same family as shell beans, such as pinto beans, black beans and kidney beans. Yet unlike their cousins, green beans' entire bean, pod and seed, can be eaten.

Green beans range in size, but they usually average four inches in length. They are usually deep emerald green in color and come to a slight point at either end. They contain tiny seeds within their thin pods.

The scientific name for green beans is Phaseolus vulgaris.

History

Green beans and other beans, such are kidney beans, navy beans and black beans are all known scientifically as Phaseolus vulgaris. They are all referred to as "common beans," probably owing to the fact that they all derived from a common bean ancestor that originated in Peru. From there, they were spread throughout South and Central America by migrating Indian tribes. They were introduced into Europe around the 16h century by Spanish explorers returning from their voyages to the New World, and subsequently were spread through many other parts of the world by Spanish and Portuguese traders. Today, the largest commercial producers of fresh green beans include the United States, China, Japan, Spain, Italy and France.
