Cabbage

Cabbage (Brassica oleracea or variants) is a leafy green biennial, grown as an annual vegetable for its dense-leaved heads. Closely related to other cole crops, such as broccoli, cauliflower and brussels sprouts, it descends from B.  oleracea var. oleracea, a wild field cabbage. Cabbage heads generally range from 1 to 8 pounds (to kg), and can be green, purple and white.
