Veronica, about 50 of mine are in containers, but I'm determined to get them all out of the containers and into the ground this year or next. No matter how large the pots are, the clems just don't do as well in pots as they do in the ground. For one thing, the roots grow like crazy, so they need to be repotted in larger containers constantly. I was keeping them in pots because of a lack of space, but now I'm thinking of just growing four or five in the spots I'd originally reserved for one, and l'll just let the different colors and shapes work together.
Sue, your photos are stunning!
