Turnips are grown mainly for their enlarged root,
although some people also enjoy eating the greens. The root
usually has a flattened globe shape and is two-toned, with
purple on the top and white on the bottom. Some cultivars
can be round or cylindrical.
Turnips are easy to confuse with rutabaga and kohlrabi,
but rutabagas are larger and more yellow on the bottom and
kohlrabi are one solid color and grow above the ground.
