Q: When my husband dug up a sweet potato vine, he discovered a tuber. Is it a real sweet potato, and is it edible?
— L.A., Warren
A: An ornamental sweet potato vine tuber is indeed a real sweet potato. The Alabama Cooperative Extension Service says the tubers are edible, but you probably don’t want to eat them. Many people think they taste unpleasant or bitter. Besides, the plant may have been exposed to pesticides applied by you or the greenhouse that grew it, the extension service notes.
You’re probably better off saving the potato in a cool, dark, dry place and planting it next spring. You can also try rooting it in a glass of water, the way many of us did when we were kids.
