Sweet, delicious green peas, also popular as garden peas, are one of the ancient cultivated vegetables grown for their delicious, nutritious green seeds. peas probably have originated in the sub-Himalayan plains of northwest india. Today, this versatile legume is one of the major commercial crops grown all over the temperate and semi – tropical regions. Peas are not actually a vegetable but a small, edible legume and as such they belong to the same family as lentils, chickpeas, beans and peanuts. Peas grow in pods on a vine and once the pod is plump, they are ripe for picking.
