Phaseolus vulgaris, the common bean, string bean, field bean, flageolet bean, French bean, garden bean, haricot bean, pop bean, or snap bean, is a herbaceous annual plant grown worldwide for its edible fruit, either the dry seed or the unripe fruit, both of which are referred to as beans. The leaf is also occasionally used as a vegetable, and the straw can be used for fodder. Along with other species of the bean genus (Phaseolus), it is classified botanically into the legume family (Fabaceae), most of whose members acquire nitrogen through an association with rhizobia, a species of nitrogen-fixing bacteria.

Yellow Wax beans are a member of the <i>Fabaceae</i> family, along with common beans, pulses and peas. "Yellow Wax" is a given name to dozens of wax bush bean varieties that individually simply happen to have different shades of yellow in appearance and variance in waxiness depending on the cultivar. Yellow Wax beans are nearly identical to Green beans in all aspects except for color. One of the most famous heritage Yellow Wax bean varieties is the Beurre De Rocquencourt Bush Wax bean, named for the rich farming region, Rocquencourt, France. It is the single most responsible bean for catalysing the popularity of the Wax bean within the 20th century. Yellow Wax beans' ancestors are native to Central and South America. Many Yellow Wax bean varieties, though, were first introduced to their respective culinary regions from Algeria. The Algerian Wax bean is responsible for the development of several varieties of Wax beans from the 18th to the 20th Century. It is considered the oldest known cultivar still in production.

Green beans, also known as string beans, snap beans in the northeastern and western United States, or ejotes in Mexico, are the unripe fruit of various cultivars of the common bean (<i>Phaseolus vulgaris</i>). 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. (Wikipedia)
