Hi Annie! I also recommend Phlomis for dry, sunny conditions. Have you tried any? Phlomis tuberosa is hardy in open ground even to Zone 4, and in your Zone you can also grow Phlomis russelliana in the open. Phlomis fruticosa (Jerusalem Sage) is hardy in Zone 6 if grown against a south wall and burlap-wrapped for winter (which I used to do when I lived in Chadds Ford, PA, and I had more energy). Also, a big plus: PA deer don't like to eat Phlomis leaves.
I'm hoping for a thunderstorm tonight or tomorrow.
Keep on blogging!
