Only one type of broccoli is generally found in markets, but a few close relatives of this vegetable are also available. Broccoli rabe has thinner stalks and is leafier, with smaller bunches of buds. It has a stronger, more bitter flavor, and all of the plant, including its leaves, is edible. Broccolini is a new vegetable that looks just like regular broccoli except that the stalks are delicate, with thin stems; the flower buds are also smaller.

Broccoli is available frozen and is sometimes included in frozen vegetable mixes.
