Purple Hull Peas chi UsaL

I would have happily assumed that purple hull beans or peas to be the black eyed peas in the American supermarket. But then, there was a packet of black eyed peas too. I guess, purple hull peas must be the first cousins of the black eyed peas. They resemble a lot. Purple hull peas have greenish outer peas with purplish tinge in the middle. When I googled, I found they have beautiful purple string beans.
