The thing is, we usually have dry summers here. Droughty, even. We had 2 stretches last summer that were hot and dry but each only lasted maybe 2 weeks. Other than that summer was cooler than normal, cloudy, and wet.
Most of my perennials are pretty drought tolerant, like coneflowers. I don't know what all this wetness will do to them in our clay soil. In a few months, I guess I'll find out the answer.
