Cauliflower Seeds

Cauliflowers are annual plants that reach about 0.5 metre (1.5 feet) tall and bear large rounded leaves that resemble collards (Brassica oleracea, variety acephala). As desired for food, the terminal cluster forms a firm, succulent ?curd,? or head, that is an immature inflorescence (cluster of flowers). The broad leaves extend far above the curd and are often tied together before harvest to shade the curd and prevent discoloration. Commercially, white cauliflower is the most common, though orange, purple, green, and brown cultivars also exist. The plants produce cross-shaped yellow flowers and bear seeds in dry capsules known as siliques.
