The radish is a root vegetable of the Brassicaceae family. The most popular part for eating is the napiform taproot, although the entire plant is edible and the tops can be used as a leaf vegetable. The skin comes in a variety of colours. Most commonly known is the round, red-skinned variety. Other varieties may have a pink, white or grey-black skin. A large, round yellow-skinned variety has a subtle taste of lemon.
