I noticed that idea of planting them in a container a few years back at the nursery's. I have quite a few of them but noticed they took a beating with our winter, I am hoping they improve. Yours looks so nice...let us know how they do over the summer months in the container. I did plant some in a bird bath years ago but the birds/chipmunks kept digging them out so I gave up on them. Maybe I will try again ...
