I started some cuttings from a sweet potato - Garnet - from the supermarket. It produced stems, branches with leaves and I broke those off and rooted those in water. Now I have rooted cuttings. It's an experiment basically. I'd enjoy them just as a decorative annual in a pot of annuals, that hangs down, but if I could actually get sweet potatoes from them, I'd love that. So I was going to use a large ceramic pot and plant just the sweet potato cuttings alone and see if they would produce potatoes. But it's such a big pot, I wonder if there is anything else I could grow with it?
I have 3 Dahlia bulbs that would love that container too, but is that a problem for the potential sweet potatoes? Or I have some leftover pepper plants or Four OClocks. Any experience with growing sweet potatoes in pots, or whether there are plants that are not good to grow as companions to them?
