Re: Sport?

It may make sense to propagate it--color sports are frequently enjoyed by rose growers, after all. Its parent 'Aloha' produced a lighter sport called Dixieland Linda or Lady Ashe ('Beadix'). Depending on the extent of the sported tissue, you might be able to do that in one move with cuttings, or it ...

Re: Sweet Spirit

Sweet Spirit held its lush, full appearance through most of July (when we had 30 continuous days of 90 degrees or higher with high night temperatures), and probably had good-looking flowers through June, but really began to defoliate from the bottom up here in August when it became wetter and slight...

Re: Early freeze in Colorado! Save my hips!

I tend to root most of my softwood and semi-hardwood cuttings of roses by first allowing them to callus in a small amount of water, either under lights or in a window sill--this helps to prevent foliar diseases like black spot from ravaging the cutting's leaves prematurely. This year, I had a stem f...

Re: Sweet Spirit

I snagged one last fall as a large plant with quite a few beautiful, large OP hips--the number of large, healthy seeds per hip and germination percentage were both good, and there were some interesting offspring with flowers in shades of rich red to salmon-pink. It has been reasonably healthy, start...

Re: Prickle free

A number of Shoup's named selections do have relatively few and/or small prickles, often due to the use of 'Basye's Blueberry' and sometimes Heritage ('AUSblush') in breeding. This one's parentage isn't recorded in HelpMeFind.com, but one or both of those could be in the mix here, too.

Re: First known yellow rose

You might get some surprising results from using 'Harison's Yellow' ("Harrisonii" on your list)--while it won't necessarily transmit bright yellow, it is capable of producing repeat-blooming offspring when crossed with modern roses and could be a fun plant for you to tinker around with. It's also a ...

Re: Scandinavian Import ID Challenge - Needle in Haystack Quest?

If R. rugosa is in its background, some of its usual morphological signatures certainly have been muted by the influence of some other species (which can certainly happen). It does look like R. spinosissima might be in the background, probably with some modern or Synstylae section rose(s) as well to...

Re: Scandinavian Import ID Challenge - Needle in Haystack Quest?

That's some interesting-looking (and sounding) rose you have, but it doesn't seem to be much like any of the ones you've listed. Did you import them all from a single nursery, or have any other clues that might help? The closest ones I've found so far still don't seem all that close to what you have...

Re: Handling cold-hardiness

Cane disease can be a major problem under certain circumstances (causing cane loss under normal exposure conditions in warmer zones, or in northern areas where there is winter protection applied, or even sometimes under natural snow cover). There is also an erratic winter dieback problem that occurs...

Re: 'Banshee' for hybridizing...

Partly from trying to tease out the ploidy of my clone, I've thrown some 'Banshee' pollen at a few different roses this spring, all tetraploids as far as I know, and have a few good-looking hips setting (along with a few failures). That foliage on your hybrid is more than a little inspiring, Tom. I'...

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?

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 ...

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.

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...
