Cauliflowers Overview

Brassica oleracea (Botrytis Group) is a plant variety commonly called Cauliflower, from which the widely consumed vegetable cauliflower is produced. Cauliflower is a cool-season annual vegetable. Grown for its premature flower buds, which are also known as a curd. This is coloured off-white, but can be purple, green or orange, with some cultivars producing these curds in complex fractal patterns. Cauliflower is grown and eaten as a cooked vegetable that contains high levels of vitamins C and K.
