Re: pictures Martin Frobisher Seedling

Duane, I don't take any pleasure in raining on your parade as the saying goes, but if 'Therese Bugnet' is the staminate parent of your selection then this is a problematic cross unless you did it as a fun experiment for whatever reason. First, 'Martin Frobisher' and 'Therese Bugnet' are obsolete ros...

Re: Video tour including Metis and Bella Nitida

Very interesting work, Joe. The several cases of assumed identity remind me of the stories I have heard about Percy Wright 'guestimating' the parentage of his hybrids from their phenotypes and nearest neighbors. Regarding the suspect Tuscany cross, it does look doubtful that it has Persian Yellow i...

Re: hardiest reblooming diploid?

'Grannie's Rose' growing at the Brooks, Alberta rose garden is likely a Damask rose. It definitely isn't 'Minette' or 'Banshee'. Healthy, vigorous, fragrant and good cold hardiness for a Zone 3 climate. I certainly would use it in a breeding program.

Re: hardiest reblooming diploid?

The 'Minette' plant I sent David Zlesak for ploidy testing came from the Rainy River region of Ontario (borders Minnesota), and has been grown there for many decades. From the research I've done I think it's a good possibilty it came with eastern Ontario settlers who homesteaded in this area in the ...

Re: hardiest reblooming diploid?

Joe, You may want to consider 'Marie Bugnet', which is classified as a Rugosa hybrid but has an unusual pedigree for one, containing a Polyantha in its lineage. This I believe made it possible, if my memory is correct, for Robert Erskine to develop a seedling of 'Marie Bugnet' that had juvenile bloo...

Re: Yellow blend rugosa hybrid

Plazbo,

When you are criticizing my comments, whether it's on the RHA Forum or HMF Roses, have the ethics and courtesy to sign your full name. Otherwise, you are being disrespectful towards me and that's not acceptable.

Re: Yellow blend rugosa hybrid

'Nyveldt's White' may be classified as a Rugosa but that's a stretch since at the most it's 25% Rosa rugosa. In my opinion only a rose cultivar having at least 50% Rosa rugosa in its parentage can be classified as a Rugosa. The pedigree of this cultivar is also highly debatable. It's unlikely a whit...

Re: Coutts #4

It's difficult to believe Coutts #4 (aka 'Unity') is a diploid, but if it is then it might be worthwhile to breed it with Rugosas (especially 'Schneezwerg') to hopefully reduce fertility problems in succeeding generations of breeding. Initially working with Coutts #4, it has to be kept in mind as a ...

Re: Anyone breeding for fall color?

The parentage of 'Michel Trudeau' is likely a cross of 'Roseraie De L'Hay and 'Marie Bugnet'. Both shubs grew relatively close to each other on this landscape site, and this 'Roseraie De L'Hay' sets a few hips each year. The seedling that was named 'Michel Trudeau' was found growing close to these t...

Re: Hardy, Everblooming Climbers

A few notes about Rosa maximowicziana in a Zone 2 climate (Saskatchewan, Canada). First, this species is surprisingly cold hardy for this zone, coming through the winters quite well. The flowers generally bloom very well each year. Of course, the shrub's very prostrate growth habit helps a lot in th...

Re: 'Chinook Sunrise' parentage

Joe, 'Oscar Peterson' - It doesn't do anything for me so I wouldn't plant it in a landscape of mine. But considering its pedigree, surprisingly it can be semi-hardy to a Zone 2 climate for at least a couple of years (more testing has to be done). Floriferous and seems to repeat quite well. Fertile a...

Re: 'Chinook Sunrise' parentage

Rob, There are many Canadian developed roses cold hardy to Zone 2 but mainly Spinosissima cultivars. 'Hazeldean', 'Prairie Peace', 'Beauty of Dropmore', 'Suzanne', etc. Interestingly, in some years 'Red Dawn x 'Suzanne' and J5 can do quite well. Others would include 'Athabasca', 'Therese Bugnet', 'C...

Rob, Absolutely I do. In fact, they are only semi-hardy to a 2b plant hardiness zone. 'Frontenac', of course, being hardier than 'Campfire' but the latter, considering its parentage ('My Hero' x 'Frontenac'), is hardier than I would expect it to be. By the way, 'Campfire' growing in Zone 2/3 can hav...

"They are also disease resistant and winter hardy to -40C meaning there are no shrinking violets in this (49th Parallel) collection." They aren't winter hardy to -40C, of course. One just has to check their parentage to determine that. In fact, they may be semi-hardy to that temperature. Or are they...

Example of Zone 5 rose cultivar crossed with Zone 3 one. 'Canadian Shield' ('My Hero' x 'Frontenac') Since I don't have personal experience with it, I have to speculate somewhat as to the cold hardiness zone of 'My Hero', but I'm thinking it's likely Zone 5 and borderline cold hardy to Zone 4.

Re: Any merits to R. woodsii ultramontana?

It's ironic Rosa woodsii is the most geographically widespread Rosa species in North America, but it hasn't contributed much to the development of roses in Canada and the U.S. 'Therese Bugnet' (Rosa blanda) being one notable exception. However, I think it has a lot of potential and therefore continu...
