Cauliflower is a variety (Botrytis Group) of Brassica oleracea in the family Brassicaceae. It reproduces by seeds. Cauliflower resembles broccoli, to which it is closely related, except with very densely packed white flower buds. According to the United States Department of Agriculture, 100 g of raw cauliflower provides 77% of an adult's DRI of vitamin C. It is also a source of dietary fiber, vitamin B6, folate, pantothenic acid, as well as small amounts of other vitamins and minerals.
