Unlike broccoli, cauliflower produces only one head per plant, called the "curd." The heads of most varieties need to be blanched for the best white color and flavor, although there are some that develop orange, green or purple heads that don't need blanching and are a little easier to grow. To produce a good head of cauliflower, you need to keep in mind that stresses such as temperatures that are too high or low, or water or nutrient stress can lead to poorly formed heads. So it's especially important to give cauliflower the best possible growing conditions.
Germination: 1/4 to 1/2" depth at 70 F to 85 F. Time to germ 5 to 10 days.
