Cole crops are one of the largest groups of temperate vegetables, comprising important crops like cauliflower (Brassica oleracea var. botrytis), cabbage (B. oleracea var. capitata), sprouting broccoli or broccoli (B. oleracea var. italica).The cruciferous vegetables, often called “cole” crops, are grown for their leaves. These are cool-season crops; they tolerate light freezes and even brief heavy freezes, but prolonged deep freezes are fatal. Though naturally biennials, they are grown as annuals.Cabbage and broccoli are used raw in salads. Cabbage is used steamed or boiled alone, or in a mixture of other vegetables as main dishes.
