This annual is grown mainly for its enlarged, crisp-tasting, edible root, but the leaves can also be consumed. The plant is a rosette of leafy greens that grows 6-8 inches tall. The leaves are best when harvested young; cook them or add raw to a mixed salad. The roots are rounded or elongated, the flesh is white, and the skins can be white, red, pink, or bicolored. They should be harvested when 1/2- 11/2 inches diameter and before they become tough and woody. They are at their spiciest when dug in hot weather or just before they go to seed
