Hi. Can you inform me about Everblooming Climbing Cecile Brunner? The bush form is wonderful. The climbing sport is crazy huge in Southern California, but generally yields one huge flush of blooms a year. I notice Heirloom Roses offers this Everblooming Cl C. Br. plant, but I can find nothing about it. Is it really more remotant than the common climber? Can it survive a zone 5b winter, where I live now? Thanks! Brian in PA.
