All parts of a beet plant are edible. The tops, or greens, can be cooked and enjoyed like spinach or turnip greens. But it is the root, the pretty part, that we prefer. While the bulbous roots are most often dark red, they can also be yellow, white and striped like a candy cane. Don't let the color fool you - even the white ones are as sweet and tasty as the red ones! Their shape can vary as well. They can be round, flat or cylindrical.
