O, that is breath-taking! I love Clbg OB so much that I am willing to overlook its' faults in my climate: some disease issues and not continuous bloom. I suspect that one problem in my climate for Clbg OB is the fact that it holds onto it's leaves and blooms during our warm winters,so when spring comes around and it does it's glorious spring flush, it feels exhausted ,gets blackspot and PM, drops its' leaves,and finally goes dormant. I am beginning to suspect that this rose and some of the noisettes can't cope with the long summer drought and heat, and the fact that in my garden they must rely on rainfall. In fact, I did just notice that almost all of the photos of Purple Mount Vernon on HMF are of plants growing in more moderate climates-climates that I believe DO benefit from summer rain.
