I am in zone 8, which may make a difference in size. I forget how old my plant is(at least 8 years) It is compact, 4 x 4, well foliated, upright but graceful. It's fairly disease resistant here. I would say repeat bloom is average. The blooms are so beautiful, fragrant, I think they are 4 or 5 inches across. Mine is in full sun. The soil is rich clay and it gets regular water. I hope it does well for you!

Thank you!
