Cauliflower
Cauliflower is a common vegetable. Many people will eat the heads and will throw away the stalk and the leaves that the head is attached to. It is a very nutritious vegetable that can be eaten raw, pickled, or cooked.
Its name is a variation of cole flower or kale flower (cole and kale being variations of the same word), an acknowledgment of its unusual place among a family of food plants which normally produces only leafy greens for eating. The Brassica oleracea species is the same species as cabbage, brussels sprouts, kale, broccoli and collard greens, though they are of different cultivar groups.
