flowering perennials in containers
I am looking for flowering perennials to put in about 15 containers that now have annual flowers. Does anyone have some suggestions for me? Maybe even some small flowering bushes? I've tried coneflowers and they died along with some daisies but the two clematis came back strong this year. I'm tired of buying annual flowers for all these containers. I need perennials. The containers are varying sizes but most are on the large size. I live in zone 5/6.
