After becoming popular in France in the 1500s, it was cultivated in Northern Europe and Britain. Today, most cauliflower is grown in the United States, France, Italy, India and China.
When growing, cauliflower starts out resembling broccoli, according to the University of Arizona. However, while broccoli opens outward to sprout green florets, cauliflower forms a compact head, called a curd, composed of undeveloped flower buds. The buds are protected from sunlight by the heavy green leaves that surround the head. This prevents chlorophyll from developing, so the head remains white.
Through selective breeding, however, several varieties of colored cauliflower are available, such as orange, purple and green. The jury is out on whether they are more nutritionally rich than the white variety.
