Broccoli is an edible green plant in the cabbage family, whose large flower head is used as a vegetable.

Broccoli has large flower heads, usually green in color, arranged in a tree-like structure on branches sprouting from a thick, edible stalk. The mass of flower heads is surrounded by leaves. Broccoli most closely resembles cauliflower, which is a different cultivar group of the same species.

Broccoli is a man-made plant, derived from careful breeding of cultivated leafy cole crops in the Northern Mediterranean in about the 6th century BCE.

Broccoli is usually boiled or steamed but may be eaten raw. Broccoli is high in vitamin C and dietary fiber; it also contains multiple nutrients with potent anti-cancer properties, such as diindolylmethane and small amounts of selenium. A single serving provides more than 30 mg of vitamin C.
