Broccoli is an edible green plant in the cabbage family, whose large flowering head, stalk and small associated leaves are eaten as a vegetable. Broccoli has large flower heads, usually dark green, arranged in a tree-like structure branching out from a thick stalk which is usually light green. The mass of flower heads is surrounded by leaves. Broccoli resembles cauliflower, which is a different but closely related cultivar group of the same species.
