Here in Zone 7b, in the mountains of AZ, whether this is a cold hardy rose depends on whether it is grown on its own roots or grafted to Dr. Huey. On its own roots, it puts out foliage quite early and suffers through many dozens of freeze-thaw cycles in the spring. On Dr Huey roots it just sits there until you are quite sure it is dead. Then just as the own root roses have completely expired from freezing and thawing in early May, it puts out new foliage and grows vigorously.

I'm in zone 7 in NC and I had the same experience this year. Mine was on Dr. Huey and I really thought the canes were dead (they looked to be turning black and everything). Then out of nowhere, it just took off like a weed and has blooms all over it. It's even grown two monster basal canes.
