Re: North American Rose ID?

Hi Matt, For another modern reference, you might also want to look at Systematic Botany (2007), 32(4): pp. 819–836. Delimiting Species Boundaries in Rosa Sect. Cinnamomeae (Rosaceae) in Eastern North America, by Simon Joly and Anne Bruneau. The data they present shed some light on the variable hybri...

Re: Rosa Helenae Hybrida Off Spring Success in NAmerican Cold Zones?es?

Yep, 'Lykkefund' has a very good scent--I would imagine that straight R. helenae does also. It's a similar fragrance to R. moschata and R. brunonii in terms of both intensity and quality. Its foliage is not overly disease resistant here, but it sets hips well, and its lack of prickles extends even t...

Re: Rosa Helenae Hybrida Off Spring Success in NAmerican Cold Zones?es?

Don, that's both good and bad news about Elizabeth Park--unfortunately, Stephen Scanniello has reported recently that the ramblers there were hit very hard by Rose Rosette Disease (see the Heritage Rose Foundation's December 2019 newsletter: https://www.heritagerosefoundation.org/). Hopefully this o...

Re: Rosa Helenae Hybrida Off Spring Success in NAmerican Cold Zones?es?

If I'm not mistaken, "Helenae Hybrida" has never been imported to North America; I am not familiar with the additional two Scandinavian crosses you mentioned, but it seems reasonable to assume that they have not yet reached this continent, either, unless they've quietly snuck into Canada as such ros...

Re: R. davidii

I noticed that some of the R. davurica photos on HMF appear to be misidentified, and others are at least questionable--those with obvious R. rugosa characteristics might just be R. x kamtschatica. The straight species as I know it (I'm familiar with one directly wild-collected clone) is upright and ...

Re: R. davidii

R. davurica might be a closer match to this FF material. I would agree that these growing season photos don't look much like any of the North American species.

Re: R. davidii

Where I work, I had ordered a plant of R. davidii from a nursery (not Forestfarm, but another Pacific NW nursery, so there's a good chance these are the same clone), and determined soon after receipt that it was misidentified. I tentatively determined the plant as R. virginiana, but have not taken a...

Re: Under-utilized species you feel might have merit

Karl, wouldn't it just be easier to freeze pollen and pollinate when the mother is blooming naturally? That would be a heck of an effort when the alternative is so much easier and more space-efficient! Whatever its exact parentage was, I once had a plant of 'Letizia Bianca' and it didn't do much for...

Re: Hardy, Everblooming Climbers

Hi Karl, I think it's fair enough to offer my experience, for whatever it's worth; most people growing various species roses won't likely have the benefit of knowing their clones' specific provenance, after all. The clone of pure R. setigera that I am most familiar with (although I have seen others ...

Re: help with i,d.?

I agree with David about asking at the store, just in case. I would really get those photos over to the Houzz forums to see if those collective eyes can't help ID this, though. And in the meantime, ready your best pick-axes, ice augers, etc. If the temperature is warm enough, maybe plain cold water ...

Re: help with i,d.?

Hmm. Still dancing around Austins, maybe take a look at The Countryman ('AUSman'); that one would potentially display this combination of traits, and would be an older Austin, too. The background ('AUSmound'/Lilian Austin x 'Comte de Chambord') is different from some other Austins, and could help ex...

Re: help with i,d.?

It's definitely not definitive! There are certainly other options out there, like old Boerner floribundas with surprisingly old-fashioned flower forms. How wide are the flowers, would you say?

Re: Hardy, Everblooming Climbers

'Applejack' is usually cane hardy in zone 4. How far it can be diluted without great loss of cane hardiness probably depends quite a bit upon what it's mated with, but a lot of Buck's roses were probably a good several generations removed from it and frankly show precious little of its influence. Ev...

Re: help with i,d.?

Can you characterize the fragrance in more detail? It looks much like an Austin--I was going to suggest 'AUSrimini' (Strawberry Hill) but then had to stop myself, because there are so many vaguely similar-looking Austins in that same vein. When dealing with an unknown Austin, the foliage, prickles a...

Re: Hardy, Everblooming Climbers

That's a pretty interesting background, maybe not quite as good as having "Hybrida" itself, but almost 'Ames 5'-like in a way--it will really be good to see if that one shows any signs of fertility, and I'm curious how much hardiness it will show there. R. majalis is often only listed to zone 4, but...

Re: Hardy, Everblooming Climbers

Riku, I missed seeing your mention of Gertrude Jekyll and thought it was interesting that you had some luck with that one, while for me it had hardiness trouble where 'Baronne Prevost' fared much better. 'Comte de Chambord' was also less successful than BP, but it was more badly affected by disease,...

Re: Hardy, Everblooming Climbers

I love 'Ross Rambler' and the sweet scent of its flowers (in contrast to superficially similar R. laxa), but have had similar problems getting it to accept applied foreign pollen even though OP hips set with ease. I can't quite remember now, but I might also have had trouble getting good pollen from...

Re: Hardy, Everblooming Climbers

Sorry Riku, I don't know why I was thinking that 'Ardoisee de Lyon' was the HP parent of 'Soleil d'Or'--that certainly colored my thinking about the potential hardiness contribution of R. foetida in that case, but it's really 'Antoine Ducher', which may well be more tender (I have never grown it). I...

Re: Hardy, Everblooming Climbers

Hey Riku, yes, I do remember that SdO experiment you conducted (impressive you were able to keep it alive so long, actually, since it blackspots upon exposure to air and defoliates 20 seconds later), but I'm just not so sure that it has significantly improved winter hardiness over its HP parent, 'Ar...
