Radishes are a root vegetable with light-colored, crisp flesh, various skin colors, and a peppery, nearly spicy flavor. The skin can be red, black, white, yellow, pink, or purple, and the shape can range from short and round to long and narrow. The parent domesticated species for all forms of radishes is Raphanus Sativa. The color and shape of the radish distinguish the many types. The radish is thought to have originated in Southeast Asia or Central Asia.
It was also utilized for food and medicine by the ancient Greeks and Romans some 2,500 years ago.
