Can You Eat a Sweet Potato Vine Tuber?

While taking apart my front porch container plantings this weekend, the question came to mind: Can you eat these cute little tubers that the ornamental sweet potato vine made?

Short answer: Yes, you can.

Longer answer: Yes, you can, but you probably don’t want to. Ornamental sweet potato vines are selected for their foliage — the lush leaves that tumble out of pots and window boxes so decoratively. The tubers are not even a consideration, and so don’t usually taste very good. If you want delicious sweet potatoes, it’s best to grow plants designated for eating.
