Teresa, although we do get some mild freezing each winter (never below 20, rarely longer than overnight) the problem with containers is keeping them wet enough during the summer. They prevent the roots from being able to seek out the water. I don't think I can add any more containers since I have to hand water them daily. That's why I was thinking that putting them in partial shade would keep them from drying out...although I don't know if the reduced sunlight would reduce to blooms.
