Answer: Part of the problem with container gardening is that the containers dry out quickly during the hot weather and the roots of the plants can actually bake when the containers are exposed to sunshine. Sometimes you can group the pots together to help shade one another, or you can place a decorative rock, bench, etc. in front of the pots so they are shaded for at least part of the afternoon. With these tactics in mind, you can plant the following heat tolerant, drought tolerant perennials in your containers:
Asclepias (Butterfly Weed); Coreopsis; Gaillardia; Liatris; Daylilies; Achillea;
Shasta Daisy; Sedum; Heliopsis; Echinacea; Buddleia (Butterfly Bush); Thyme.
Best wishes with your container garden!
