All organic cauliflower is healthy and loaded with fiber, folate and vitamin C. Most people think of cauliflower as having white or off-white curd. But more nutritious varieties are available in orange, green and purple colors. Orange cauliflower comes in "cheddar" and "orange bouquet" varieties (this picture shows the "cheddar" cauliflower I bought this morning at the farmer's market), and contain 25 times as much vitamin A as white cauliflower. Green cauliflower is available in "alverda" and "green goddess" varieties. Purple cauliflower is available in "graffiti" and "purple cape" varieties, and contains the antioxidant group anthocyanin. (Note that true purple cauliflower is different from a vegetable sold as "purple cauliflower" in the UK, which is actually a variety of broccoli.)
