Re: squirrels eating hips

I had a four and a half year war with squirrels, and for the most part, lost. A cat or two with a pellet gun for backup might do, if the logistics allow. An owl decoy was very marginally effective, and then only when I moved it often. (It eventually ended up badly gnawed by them!) Ultrasound did not...

Re: Observations on breeding Damasks

Thank you for such a detailed account of your efforts. Do crosses of the oldest damasks produce some seedlings with fedtschenkoana traits dominating? Since that species is supposed to be a big part of the ancestry of the original damasks, I speculate, based purely on research, not experience, that ...

Re: Pedigree breeding and diversity.

Well, there goes one of my lines of research. I found a reference by a Portuguese explorer from the 1500s, who stayed in a port city on the northwest coast of India during the months of Nov-Feb, to a religious ritual he'd attended which featured roses on the altar. Aha, I thought, evidence of rebloo...

Re: Observations on breeding Damasks

Research has shown that there is considerable genetic variation in the old Damask roses of Iran. This seems to contradict the 3-species hypothesis because the distinctive characters of this "species" apparently hang together in subsequent generations. Perhaps. I saw your post while previewing an an...

Re: Pedigree breeding and diversity.

Interesting! There is also supposed to be some multiflora and luciae var luciae in the Crimson Chinas. Could it be that 'Old Blush' is not the other parent? Oh! I hadn't heard that. A common ancestor wouldn't surprise me at all. Have you read any of the theories about a rose called Ward Sebba'auy? ...

Observations on breeding Damasks

This aren't a whole lot of people breeding these anymore, but I'd hope that others who have bred them will contribute what they can, so that those who want to try it in the future will have a good place to get started. *********************************** We don't know for sure which was the original...

Re: Pedigree breeding and diversity.

I do take exception to the old assumption that a Damask rose was a parent of the Bourbons. The historical and botanical evidence points to a Centifolia as the European rose accidentally married with a China. The Rose Edouard would probably have been a 2nd or later generation derivative. IIRC there'...

Re: Pedigree breeding and diversity.

I'm replying only to the last paragraph, since we're on the same page up to that point. I think that going closer to species is a way to breed tough roses, but absolutely didn't mean to suggest that it's the only way. And going back to a species that does badly where you live, might be no better tha...

Re: Pedigree breeding and diversity.

Steven; I've been trying just the approach you bring up, and not all of the results were good, but I've found some quite encouraging. Half of my posts over the last few years have included complaints about drought, and the hungry wildlife it brought into my yard. Most of my roses also got insufficie...

Re: Any advice on pollinating synstylae?

Thanks, I was trying to steer clear of the q-tip approach, since most of the pollen parents I'm working with are very stingy, but will try both of those right away. :)

Re: Rosette Disease

Does RRD particularly affect R. multiflora and it's derivatives? If so, that would seem to endanger polyanthas, floribundas, miniatures and perhaps grandifloras. Are other ancestors of modern roses affected? Are there any that are not affected? Multiflora is especially vulnerable, which was why som...

Any advice on pollinating synstylae?

My usual pollination technique is to take a coated fingertip (and usually a few anthers), stick them into the middle of the bloom, and rub it around a little. This obviously won't work with my Single Musk, or any rose with similar reproductive anatomy.

What methods have worked out for you?

Re: Rosette Disease

Tangentially, does anyone have any experience with Larry Daniels or it's progenitor, Grandma's Hat, either as seed or pollen sources? I didn't do any real planned breeding with it, but I did grow out some seedlings just to see what happened. I still have one (Grandma's Hat x self?) that distinguish...

Re: Rosette Disease

Hi Steven, and welcome to the forum! Those hips are what we'd call OP, meaning open pollinated. Although there are some roses which readily pollinate themselves, most won't do so very much, so (assuming bees are not yet extinct in the area) many seedlings you'd get would likely be hybrids with other...

Re: The Effect of Rose Root Size on Drought Stress Tolerance

I would like to see a similar study done to correlate mildew susceptibility with root mass/vigour. Having kept 100+ cultivars under drought conditions for 5 years, then having moved the surviving plants to much better conditions, I'd absolutely agree that there's a correlation, because dozens of my...

Re: Nineteenth century French rose (Rosa sp.) germplasm show

I found some of the data they used quite interesting, in that they determined ploidy for a number of roses, some of which hadn't been tested before, and others which had, but where the new results were different from the old. Some I didn't expect: Archiduc Charles (Gallica) 3x Cardinal de Richelieu ...
