Colored Cauliflower is available in green (also known as Broccoflower), purple and orange varieties. Although it may look different than the popular white cauliflower, the taste is just the same: mild, sweet and nutty. The orange and purple cauliflower are higher in antioxidants than regular white cauliflower. Purple cauliflower’s true origin is not known, but the purple color is natural. It is the antioxidant anthocyanin that gives it the purple pigment.
