I plant a number of perennials & even roses in containers. Since there is no way to over winter them here Zone 3, left on their own, I transplant anything I want to overwinter into the vegi garden. I have had great success with herbs, roses- even the ones that are Zone 5 & alpine strawberries that spent the summers in a strawberry pot. I take the plants out of the container & try not to disturb the roots too much. Come spring, they are back in containers. I use peat moss for mulch & work that into the garden in the spring. Calgary has major fluctuating temps in the winter with the Chinooks & it is hard on all plants. We have very little snow that stays for the season. Here's a pic of my stuff overwintering in the vegi patch.
