You can even eat this type of flowering cabbage if you don't mind a bit of bitterness. Enjoy colorful bursts of pinks and purples in your garden by planting these large heads of cabbage. The cooler it gets, the more you'll notice color emanating from the foliage. Plants should survive well into the winter months until it becomes too cold.
