I selected several different types of plants. The main plants are evergreen trees and shrubs that can serve as privacy screens and winter color in the future: Arborvitae and Blue Spruce. I also selected a couple heucheras because they retain their foliage throughout the winter. After buying a couple 9 packs of ornamental kale I was all done with selecting the plants.
When planting shrubs, trees, and perennials always check the root systems. Often the root systems have been inside their pots for a while and need to be loosened to encourage good growth. If you don't loosen them the roots can circle the pot and become girdled. Usually the roots are easy to loosen by rubbing around the root system but you may need to cut them with a sharp knife if they are too pot bound.
After planting I mixed the pots up with pumpkins from our Halloween decorations. When the pumpkins begin to fade (or rot) and Thanksgiving passes we'll remove them and add Christmas lights to the trees and a few little decorations that my kids will enjoy setting up!
As long as the ground can be dug this winter we'll be able to plant the trees in the ground. If you have fall berries, like holly, you could add a little more color to the design that will last all the way through the winter!
