Disclaimer: I'm not sure. This might very well be this rose. I found it in the garden we bought from the heirs of the deceased owner, so there is no way now of positively identifying it. Nothing on HMF looks more likely (I searched literally for weeks). The rose is very close to the few pictures here, but apparently it's no longer commercially available, and it was introduced from a breeder in the Hamburg region (also, it seems, no longer active), so it's really quite possible. That's all I can say. Anybody got a better match, I'm all ears. Our second garden in Hamburg, Germany (Z8a), 2021-6-21.
