Mystery Tubers in Rental Garden: Sweet Potato? Peony? Potato?

A renter digging a vegetable garden found numerous tubers resembling sweet potatoes but with white flesh. They left a few growing and sent a photo of new growth.

Expert Possibilities: Without flowers, identification is guesswork. Could be ornamental sweet potato vine, a potato variety, or even peony tubers. Wait for flowering, then send photos of the blooms. Alternatively, take a tuber and foliage sample to a local garden center. They can identify it and advise if it's edible or ornamental.
