I'm learning it the hard way, for it stands part of the day (heavy) shade from oaks and Yew. It survives despite the past hot dry years. It flowers a bit, but doesn't thrive. It didn't die though. It stays over there, because there is a row of red climbing roses along the fence. But will cut off about a meter of the Yew.
I have always been afraid to try many of the climbing sports of hybrid teas as they suffer a lot of winter damage here in Iowa (zone 5b). I decided to try Climbing Crimson Glory because the bush form is my favorite rose and I wanted to add a little more height to it. I was not disappointed. My plant is grown on its own roots and each year it comes back stronger than the previous year. It is now entering its fourth year in my garden and it came through the coldest winter (since I have grown it) with more and longer good canes and stronger spring growth than the previous years. The flowering does not disappoint either. It blooms consistantly and at all heights with the same color, form, and fragrance as the bush form. I do not hesitate to recommend this rose to anyone wishing to try their hand at a climbing hybrid tea. You must try this rose!!!!
