This is a fascinating rose, it reminds me of Papa Meilland and Louis XIV. It looks like Palatine also carries it, but it is sold out. I wonder if a zone change is called for? It has been growing at the E.M. Mills garden in zone 5 for many years, Palatine has it listed as zone 5b+, although I would advise 6" winter mulch there because it does die back to the snow line.
