You don't have much to pick from:

himmelsauge

Perennial Blue

Veilchenblau

Bleu Magenta - I had/have this rose through Heirloom, had/has viruses, attempted to shovel prune but keeps coming back from the roots. May have earned life through that alone.

What about Quicksilver? It's a Kordes Arborose selection, ADR and has been highly recommended on this forum, especially by Moses. He recently wrote about it on the Organic Rose Forum if you want to go check there. I'll try to post a link.

Thank you Chris. I may have read his post too quickly and jumped to that conclusion. Mea Culpa! I'll have to re-read it as he may have said it was an ADR of the future. In any case, it's a stunner and I'm already planning to put it in my from with another lilac rose I'm growing. Heavy cold soil describes my soil to a T! : ))

No you read it right, but Moses may be confusing it with something else. I think it is unlikely it will ever be entered in ADR and maybe it it is not quite resistant of black spot as I have a few reports of very small amounts of black spot in Vancouver BC this spring. They said it occurred in early spring on a young plant but then cleared up quickly. It has always been spotless here. I have always loved this rose and have planted a few more on my fence on the street this spring. I have it planted behind Earth Angel and it makes a nice combination.

ooo gad, I hope that Kordes will decide to release this beauty here in Europe. What are they waiting for? It seems to do so well in so many areas of the USA, which has a much, much harsher climate in general than Europe (greater cold and heat). It would probably do great here in the south...And the colour is so rare, so sought-after...the only climber I've ever seen that is near to that colour is Azubis,and as a plant and bloomer, Azubis is leaving me pretty under-whelmed,at least for these first years that I've had it.
