Also known as ramps and rampion (and in French, raiponce), rapunzel (Campanula rapunculus) grows wild in the fields but, as the story says, is easily cultivated in the garden. Roots are eaten raw or cooked like any other root vegetable; the leaves may be eaten raw as a salad or prepared like spinach.
