A cool-season biennial crucifer, Brassica oleracea var. italica, of Mediterranean origin, belonging to the plant order Papaverales. Broccoli is grown for its thick branching flower stalks which terminate in clusters of loose green flower buds (see illus.). Stalks and buds are cooked as a vegetable or may be processed in either canned or frozen form. Cultural practices for broccoli are similar to those used for cabbage.
