Purple, Orange and Green Cauliflower appear identical to White Cauliflower, except for their color. They are all members of the very large family of brassica. However, Purple Cauliflower gets its color from anthocyanin, a flavonoid which is an antioxidant also found in red wine. Orange cauliflower contains Beta-carotene, a precursor to Vitamin A, which gives the orange cauliflower additional levels of vitamin A not found in the other varieties. Green Cauliflower, which is often known as Broccoflower, is highly nutritious. It contains more protein than broccoli or white cauliflower. All of these variations of cauliflower are an excellent source of vitamin C. They also contain folate, potassium and dietary fiber. Cauliflower is also low in calories, containing only about thirteen for every three florets. Enjoy this cauliflower raw or steam it to protect its color, which is loved for its vivid presentation as well as its good taste and nourishment.
