Cabbage is a leafy green or purple biennial plant, grown as an annual vegetable crop for its dense-leaved heads. Closely related to other cole crops, such as broccoli, cauliflower, and Brussels sprouts.
Smooth-leafed firm-headed green cabbages are the most common, with smooth-leafed red and crinkle-leafed savoy cabbages of both colors seen less frequently.
It is difficult to trace the exact history of cabbage, but it was most likely domesticated somewhere in Europe before 1000 BC, although savoys were not developed until the 16th century. By the Middle Ages, it had become a prominent part of European cuisine. Cabbage heads are generally picked during the first year of the plants’ life cycles, but those intended for seed are allowed to grow a second year. Cabbage is an excellent source of vitamin K, vitamin C and fiber, containing more than 20% of the Daily Value (DV) for each of these nutrients per serving (Cabbage is also a good source of vitamin B6 and folate.)
