Broccoli is in the same Brassicaceae (cruciferous) family as cabbage, Brussels sprouts and cauliflower. Because broccoli looks very similar to cauliflower, some people call cauliflower "white broccoli". However, broccoli and cauliflower are two different vegetables. There is also a hybrid vegetable called broccoflower that is a cross between broccoli and cauliflower. Broccoflower originated in Holland. It looks like light-green cauliflower and has a mild flavor.
