Kohlrabi is a cabbage relative. grown for the turnip-like enlargement of the stem just above ground level. Plants are grown from seed, and must be grown rapidly for good quality "bulbs." Leaves rise from the enlarged stem. The enlargement is globose or flattened, and 2 to 3 inches across at harvest. The "bulbs" are tender and succulent if rapidly grown and harvested, but become tough and fibrous with age. For eating, the peel is removed, and the interior sliced or diced and boiled.
Production in the U.S.: 147 acres reported in 1954 census. No later data. Mainly in home gardens.
Use: Fresh or cooked vegetable.
Part of plant consumed: Enlarged, bulb-like stem, after peeling.
