Bregingew, it is difficult to answer this question with certainty, but I think it is likely. I see little reason for doubt at the moment. Depending on conditions like warm days and cold nights, ‘Ispahan’ also has sometimes mildew here, but the infestation is mostly temporary and finally it disappears completely. In my opinion, this is therefore not a criterion for exclusion.
Unfortunately, a rejuvenating pruning last year and the struggling with the onset of winter with night frosts for many-many days inhibit the undisturbed development of nature so far. As a result, the growing behavior of the entire vegetation has come to an abrupt halt. Nevertheless, I have tried to capture the growth and leaf character of ‘Ispahan’ at the actual stage. Perhaps the enclosed shots and the link with further close-ups can give you a little more view for comparison. As soon as the flowers are open, we can compare them with each other.
Upon closer inspection, it also appears that the flower buds are too glandular to be ‘Ispahan’.
For what it’s worth, we are also in the middle of mildew-inducing weather at the moment, and my ‘Ispahan’ is still as clean as a whistle.
Well this is obviously not ispahan, i am not sure what it is. I got it from high country roses and their old rose selection is limited. Im gonna do some more sleuthing
It helps to know that it came from High Country. Based on that, I would maybe suggest ‘Orpheline de Juillet’.

I agree with that assessment, seems to be the only match
I’ve got 2 seedlings from the 8 OP seeds I got from 3 hips that set on Comte de Chambord last year. One seedling stays small and makes a lot of very short nodes. It looks a bit like a witches broom, I’ve seen this with a number of seedlings in other crosses and I tend to throw them away. It looks like a growth issue.
The other seedling is growing vigorously and is healthy as for now. Since it is a Portland it will probably start flowering once it is fully grown. In 2 or 3 years maybe. I’ve put it outside this week. I’ll see if it gets sick or not. The powdery mildew season has not begun yet. I’ve got a lot of false mildew and blackspot in my garden, some older varieties aren’t that resistant anymore to the newer kinds of fungus. It is raining a lot in Belgium at the moment.
Anyhow, I’ll keep you guys posted on how it is doing in a few months. I usually loose 30-60% of my seedlings to disease once they get planted outside in their first year. Depends on the crosses. So there is a high chance this one will succumb to disease. But for now, it is doing good.
Were you able to keep one of the OP seedlings of Ispahan you had in 2023?
I also wanted to report from my side. A similar thought. Nice to hear your message. I’ll keep my hopes up that all ends very well with your rare seedling.
Back to your question: No, unfortunately not. I only had one seedling, which was promising and at first healthy and vigorous, so I had high hopes for it, as it seemed somehow special. But even last year it showed a certain susceptibility to mildew. As there are no recorded offsprings of ‘Ispahan’ so far, I was willing to tolerate this imperfection to this slight degree for the time being in the expectation that it would disappear as the plant increasingly matures. This year again the spring time with its late frosts was ultimately too harsh a test for this seedling. Moreover, the grafting with a too early sprouting also fell victim to it.
My experience shows time and again that OGR seedlings take considerably longer to develop. If unfavourable weather conditions occur during these prolonged development phases, which appear cumulatively here in the last 2-3 years , the seedlings usually still have too little substance to counter them with resistance, even though the roots are quite well developed. One main reason is of course, as you already stated, if the genes don’t really fit together.
Well, it’s a shame, but losing is part of the match. I’ll try it this year again and in the meantime I’m looking forward to seeing what happens next for you. Good luck!
Great news on the Comte de Chambord! I have been using all it’s pollen so can’t wait for OP hips myself.
Shame about Ispahan, however hopefully once it’s more developed it will shake of it’s mildew problems… Mine is in the ground and I have not been deadheading it. Hopefully I get a hip
