Cabbage (Brassica oleracea var. capitata) is a small, leafy biennial producing a compact globular mass of smooth or crinkled leaves wrapped over each other known as head. The stem is short and stout. Plants flower generally after winter. The intensity of flowering depends upon the age of the plants and the period for which they are exposed to low temperatures. Cultivation of cabbage is done mainly on sandy to heavy soils rich in organic matter.
