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 at nursery san marcos ca and consumption of unripened pea pods, as is done with snow peas or sugar snap peas.
