Re: Types of repeat-flowering in roses

That's definitely not an example I would rely upon to clarify the movement of the copia allele without first being absolutely certain of the material and its ID! The name 'Rose du Roi à Fleurs Pourpres' has been used widely for at least two very different roses, one of them clearly quite modern in i...

Re: Types of repeat-flowering in roses

There is a 2019 reference listed at HelpMeFind.com (the most recent one, for the moment) indicating that DNA testing has confirmed 'Autumn Damask' as a direct parent of 'Stanwell Perpetual'. If that is true, and if RoKSN-copia is somehow present in 'Stanwell Perpetual', it would have needed to be pr...

Re: Types of repeat-flowering in roses

That's an interesting cross. I wonder what the intention was; it's a bit sad to read that it has no fragrance. I wouldn't guess that the R. moschata used in the breeding of Noisettes is any different from what we have today--I haven't detected evidence of multiple independent introductions of that s...

Re: Can anyone comment on 'Borderer'?

Belinda's Dream was no dream for me in the Mid-Atlantic, either. I've tried it twice and had the same result each time. On the other hand, I know someone who gardens in a nearby town who had no issues with it whatsoever... I would imagine that it boils down to the disease strains we've accumulated. ...

Re: First R. setigera Results

I would have hoped for that to work, too, but David's second to last sentence suggests that approach might also prove fruitless. It's possible that there is no way to get there through conventional breeding, of course.

Re: First R. setigera Results

Thanks so much for the further explanation, David--I had no idea that R. setigera pollen isn't readily accepted by other roses! It would be neat to find out what the underlying mechanisms are; it's hard to imagine that it confers an evolutionary advantage if only the pollen is faithful to the specie...

Re: First R. setigera Results

David, thanks for making and posting that video! It's fascinating to see the phenotypic diversity generated from that selfing event, and the tetraploid R. setigera is interesting and potentially useful. Was the functionally staminate (or pistillate) nature affected in any way by the chromosome doubl...

Re: Any experiences with these roses from Burlington's?

I'm a bit on the fence about Blue Mist so far--the small flowers are cute/interesting, but the plant is overall not extremely clean here during the summer-fall season, although the plant is tough and will certainly not die just because it loses leaves. The flowers are really tiny, and while the plan...

Re: Experience with mini's?: Lavender Delight

I'm just outside of DC, and black spot is definitely the number one disease problem here. I wouldn't say that Earth Angel is necessarily healthier than Knock Out here, judging from the Knock Out roses growing around here that don't appear to show much if any fall BS (I don't grow Knock Out myself, s...

Re: Can anyone comment on 'Borderer'?

I'm fairly certain that I received this one from Rogue Valley, but I recall that it had disappointing disease resistance (either black spot or something similar); I'm not sure if it's still with me, but I don't think I still have it. I did not try to use it in any crosses.

Re: Types of repeat-flowering in roses

'Stanwell Perpetual' can be nearly continuous in its flowering, but it varies by clone/rootstock/growing conditions; it is sometimes mocked in the U.S. as "Stanwell Eventual" for this reason, but some plants really do bloom very frequently and over a long season. If the authors detected RoKSN-copia ...

Re: Experience with mini's?: Lavender Delight

Philip, all of the Kordes roses on your list that I've grown get at least some black spot for me, although I haven't had them all for the same amount of time. They probably do better elsewhere, but in my garden, if a rose can possibly get black spot, it will. --Earth Angel -- still in a pot, growing...

Re: The Bishop

It seems plausible that this is 'The Bishop', but there are quite a few hybrid Chinas of vaguely similar appearance that can be frustratingly difficult to tell apart with absolute certainty, especially if they aren't growing side-by-side under the same conditions. Many of that class are quite steril...

Re: Types of repeat-flowering in roses

Unfortunately, I believe the authors of that study made an error in assuming that 'Stanwell Perpetual' contains the RoKSN-copia allele. Evidently, they determined that based on its HelpMeFind entry, which may indicate that it flowers continuously, but I'm certain that the mode of flowering and its g...

Re: Experience with mini's?: Lavender Delight

I have no experience with Lavender Delight, but are you sure it's worthy of being called "fragrant"? HMF calls it "slightly fragrant", which usually means "detectable" and little more. The parentage doesn't really suggest to me that it should be better than that, either. As for your second and proba...

Re: First R. setigera Results

Both the R. setigera and R. maximowicziana clones I know are fairly disease-prone here in the Mid-Atlantic; they sometimes give the appearance of health if they manage to keep growing later into the season, but the older and lower foliage becomes diseased. The plants are otherwise rampant enough to ...

I can't comment on its hardiness where I live now, but the answer to your question might depend on whether anyone answering (or you!) grows the real 'Bourbon Queen'. The rose that I purchased from ARE is a subtly striped once-blooming creature that doesn't really look or smell like other Bourbons to...

Re: J.B.M. Camm or cold hardier bourbons?

I don't think that information is very likely to come to light, unfortunately. The seed parent might be extinct, or floating around under some other identity, and the pollen donor was never known or even guessed at. The inheritance of cold hardiness probably isn't so straightforward in the first pla...

Re: J.B.M. Camm or cold hardier bourbons?

We usually had reliable and long-lasting snow cover, too, which is probably why the plant survived for so many years (20+). It was also growing at the base of an oak tree, which might have helped a little, but I'm not sure. According to HelpMeFind.com, the Swedish Rose Society recommends it for nort...
