AJ: I am not sure if that works. Rocotos have the perfect grow for hanging baskets imo abd a lot of chinense would be good for that, too. Rocotos need more shade in the beginning, but after they're hardened off properly, they need full sunlight and will do really well and grow really wide.
olesmokey: First of all, welcome!
The size of the pod depends on the size of the basket, but you don't need a really large pot to grow a nice plant if it gets plenty of sunlight.
