Perennials in containers
I would like to experiment with perennials in containers. Does anyone have experience with this? I am in zone 4 but maybe it is a five now. I will winter the pots in the garage. I am hoping the plants will get a head start in the spring. I am curious what WI zone 4 gardeners have tried. I have read that I should use plants that are zone 3 and I will need to repot each spring.
