Pisum sativum (garden pea)
Pea is a member of the galegoid (cool-season) legume clade. This annual grain legume crop is widely cultivated in northern temperate regions, and is well-loved by gardeners as an easily-grown vegetable that is nutritious and tasty (and actually seems to be enjoyed by most kids!). Besides their use as a fresh or canned green vegetable, peas are also grown for animal fodder, and for consumption as a split dry pulse or dal (used much like lentil). Peas are genetically highly diverse, with genetic contributions coming from three interfertile species or subspecies native to the Mediterranean basin and the Near East: Pisum sativum, P. fulvum, and P. arvense. The former is the primary genetic contributor to the garden pea (including snow- and sugar-snap types); while P. fulvum is the little-used "tawny" or "yellow" pea, and P. arvense is especially used as for cover crop and forage.
