I am growing cauliflower for the first time. I read that it must be blanched to reach its best quality. A. Blanching of cauliflower means protecting the heads from sunlight. Unblanched heads will be yellowish green, while blanched heads are pure white. When the head begins to enlarge, pull the outer leaves over the head and tie them together with a rubber band or soft twine.
Purple cauliflower is actually a type of broccoli that is purple.
It resembles cauliflower's appearance and does not require blanching. The purple head turns green upon cooking. This condition is caused by downy mildew, which is brought on by wet conditions. It can be controlled by a suggested fungicide. A. Cauliflower grows better in the fall than in the spring.
