Cauliflower comes in several colors other than white, including yellow, green and purple! Not only is this beautiful, but darker varieties, such as green or purple, can contain up to 25% more vitamin C than traditional cauliflower. This is due to a beta carotene mutation that gives the plants their beautiful hues. However, no need to fret if your grocery store only has white cauliflower heads. The traditional variety has 90% of your vitamin C needs.
