I have a few clematis plants that I bought from Walmart and Costco. I didn't expect any of them to actually grow but they are! I plan to grow them in containers to prevent the condo landscapers from killing them. I do wonder if I can drastically prune them back each year, what size pot they need and what would be a good "support" for them?
2 Red Cardinal
2 Miss Bateman
1 Nelly Mosier
1 Venosa Violacea
Both Miss Bateman are growing great. One Red Cardinal is growing great and the other is just getting started. Nelly is starting to grow well and the last one is too new to know if it'll actually grow.
