kohlrabi [Ger. partly from Ital.,=turnip cabbage], plant (Brassica caulorapa, sometimes classified as var. caulorapa of the cabbage species) of the family Cruciferae (mustard family), with an edible, turniplike, swollen stem. It is a cool-weather plant grown more in Europe, where some varieties are used for fodder, than in America. The flavor is more delicate than that of some of the other cabbage plants. Kohlrabi is classified in the division Magnoliophyta, class Magnoliopsida, order Capparales, family Cruciferae.

Form of cabbage (Brassica oleracea, Gongylodes group) of the mustard family, which originated in Europe. Its most distinctive feature is the greatly enlarged, globular to slightly flattened stem that grows just above the soil. Its flesh resembles that of a turnip but is sweeter and milder. Low in calories, kohlrabi is an excellent source of vitamin C, minerals, and dietary bulk. The young tender leaves may be eaten as greens; the thickened stem is served raw or cooked. Though not widely grown commercially, it is popular in some regions.
