I’m growing a purple variety of cauliflower this year. Although the true wild origin is not quite known, this heirloom variety comes from Sicily, another purple variety exists from S. Africa. The purple color is naturally occurring, caused by the presence of anthocyanins, a group of antioxidants which can also be found in red cabbage and red wine.
Cauliflower is rich in vitamin C. A half cup of florets provides nearly half of ones daily requirement. Cauliflower is also a good source of fiber, vitamin A, folate, calcium and potassium as well as selenium, which works with Vitamin C to boost the immune system. Cruciferous vegetables such as cauliflower are known for their high levels of cancer-fighting phytochemicals know as glucosinolates.
