The leaves, stems, and tubers of sweet potato vine are not toxic. The tubers are edible, but ornamental varieties were bred to produce lovely foliage, not a delicious crop. If you want to eat the tubers, it’s better to plant a variety specifically meant for food production. The seeds are toxic because they contain a hallucinogenic compound similar to LSD. This chemical has neurological effects on adults, children, cats, dogs, and other mammals.
