Answer: In my experience, most of these perennials would do best planted in the garden. If that is not an option you could try the oenothera, delosperma and sedum in the window boxes as they handle fast drainage, are drought tolerant and do well in a lean or less fertile soil. Most of the others will need larger, deeper containers; maybe a nursery size two gallon or so. This is especially true if you want to overwinter them successfully outdoors, and in that case you will need weatherproof containers as well. The Lonicera will need something even larger, depending if it is a shrub or a vining form. As a shrub it might eventually need a half barrel sized container, as a vine it might last for a while in a three gallon however as it puts on size it will need a larger container as well. Make sure you use a good quality potting mix and that the containers have functioning drainage holes in the bottom.
