I suppose that "technically" these could be houseplants, but mine are so ginormous that they are in the greenhouse in the winter and outside in the summer. I don't keep any plants in the house in the winter because the air is too dry and I have 5 kittycats that would LOVE to decimate them. And the plants are too big.
The chestnut vine has a trellis in the pot..........there is so much "vine" that you can't see it. The others have obelisks of some sort.
