Cauliflower

Cauliflower is one of several vegetables cultivated from the species Brassica oleracea in the genus Brassica, which is in the Brassicaceae family. Cauliflower usually grows with one main stem that carries a large, rounded "head" made of tightly clustered, immature white or off-white flower buds called the "curd". Typically, only the "head" is eaten.
