I've long since lost the tag for this one. I purchased the plant last summer on clearance. I divided it over the winter, but only one survived. The blooms are 12" across. I need to give it more sun. The Japanese Beetles are doing a number on the leaves this year.
Speaking of sun, the gully receives a lot more early morning light.
This fall I will have to do something about the ivy, periwinkle, and trees from "heaven". I've tried RoundUp in the past to no avail.
