This rose is in its second year in my garden (Malta, z11).
The first year it had a main flush in May and then produced a single flower in the fall.
This year it had an earlier spring flush in April. It then produced a very light rebloom in early June. Now, in early August, I am seeing a cluster of flowerbuds forming on one branch.
The flowers from these flushes have less petals than the first ones, and ar a little darker in color, but the fragrance is just as wonderful.

I have to say I'm a little confused about Fedtschenkoana being the pollen parent of the Damasks.

While I am in no way any kind of genetics expert, and indeed I am only just now starting to grasp some of the very basics, I do feel that in this instance things do not add up for me, no matter what way around I think of this - and this is why.

According to Hurst's septet theory (which I don't believe has been debunked, but please correct me if I'm wrong) and all the scientific (including genetic studies) discussions that I have found by all manner of people far more qualified than me, R. Moshata is described as an A septet diploid, R. Gallica as an A and C septet tetraploid, and R. Fedtschenkoana as a B and D septet tetraploid. These designations would fit with all the characteristics and traits of the three roses in question, so no problems there.

Now as I understand this, the initial cross between Moschata X Gallica would result in a triploid hybrid (fertile or otherwise, but that is not really relevant here). So far so reasonable. But- if this hybrid was then pollinated by Fedtschenkoana, surely the result would be something along the lines of an irregular A, B, C, D septet tetraploid - somewhat like the original seedling from Pernet Ducher's cross that subsequently led to Soleil d'Or. (Or even something like an A, A, B, C, D, pentaploid?) Yet nowhere have I seen this fact discussed, let alone explained.

Am I missing something, or does that not add up with the finding of all 4 of the oldest of the Damasks as A and C septet tetraploids? Where did the B and D go?!

Any thoughts? Much obliged in advance.

I've pinned this comment on the Fedtschenkoana page as well.
