Is cauliflower is a leaf or flower?

A cauliflower is a flower. It is a modified inflorescence, which means that it is a cluster of flowers that have been modified to form a head. The head is made up of small, white flowers that are arranged in a spiral pattern. The flowers are surrounded by a layer of green leaves that protect them from damage. When cauliflower is harvested, the head is cut off the plant and the leaves are removed. The head can then be eaten fresh, cooked, or pickled.
