^ That is one excellent idea @thommyjo -- there are few plants that are sustainable through the winter in above ground planters unless there is a specific effort made to protect root-zone material. There are some, however, and these could be the basis for a starting point that could then be added to with annuals for summer color. I made a list of these possibilities in my zone 3 + 4 thread makings for vertical planters for Old Strathcona -- https://edmonton.skyrisecities.com/...athcona-the-garneau-real-estate.30154/page-19
