New Dawn is thriving in my backyard(which, being lakeside,tends to lean towards zone 6b). Her long, highly thorny arms are heading up a cottonwood so the BIG show of blooms come late spring,scattered blooms thru out summer. NEVER seen any Blackspot on her..this hardy rose had a foot or more of water at her base for 2+weeks, flood of June 2015. She thrived!
