Cauliflower White Crown 45 days-Cauliflower is broccoli’s creamy cousin. It has a tightly packed flower head, called curd, rich in iron and vitamins A,B, and C. To grow creamy white cauliflower (rather than slightly yellow heads), use this gardening tip: when curds start to form, tie up the inner leaves or break them over the curd and keep leaves in place until ready to harvest.
