Snowball Cauliflower (Brassica oleracea var. botrytis) is a classic heirloom cauliflower variety known for its dependable production of medium-sized, dense, and snow-white heads. Developed in France, Snowball is particularly valued for its self-blanching trait, which keeps heads protected and retains their color without requiring leaf tying. This variety is resistant to downy mildew and thrives in cooler weather, making it ideal for fall and spring crops.
