Year round outdoor containers for Chicago
I would like to know what plants, either flowers or herbs, can stay in a container outdoors in Chicago year round? A lot of recommendations are to either bury the container in the winter so the temperature stays fairly even, or to bring the container indoors during the winter. I don't want to do either of those. i would like to have container plants that I can leave outdoors, in Chicago, even through winters like the one we just had. Any suggestions? Thank you.
