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...

Re: 'Chinook Sunrise' parentage

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...

Re: 'Chinook Sunrise' parentage

"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...

Re: experience with any of these in breeding (cold hardy reds & yellows)???

Philip, Letter from Robert Simonet to Percy Wright September 2/1952. "It ('Red Dawn') has the same growth as New Dawn and is probably no hardier but has not been tested." 'Red Dawn' appears to be a shrub rather than a Climber like 'New Dawn'. John Wallace and Frank Skinner (Canadian nurserymen) were...

Re: experience with any of these in breeding (cold hardy reds & yellows)???

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. 'Fron...

Re: experience with any of these in breeding (cold hardy reds & yellows)???

'Morden Centennial' (pink) - In my opinion the best of the Parkland series of roses for breeding purposes. Very fertile as a pistillate parent and the seeds germinate easily. It produces seedlings having very attractive flowers of excellent form when combined with the Explorer 'John Davis', for exam...

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...

Re: Percy Wright's roses

Warren, Canadian Prairie rose breeders continue to work with some of Percy Wright's rose cultivars in breeding programs, particularly using 'Hazeldean' and 'Yellow Altai' (sister seedling of 'Hazeldean'). I think I've expressed this before - that I think it's unfortunate 'Hazeldean' wasn't combined ...

Re: cold-hardy breeders

I was surprised that although this business will probably be no longer within a couple of years it continues to propagate and market roses including 'La Sevillana'. So it's probably a source for you if you...

'Walter Schowalter' rose

Recently I was reading some of David Austin's book The English Roses (Third Edition, 2017). I was particularly interested in his account of breeding Rosa alba cultivars with modern roses. 'Shropshire Lass' was the first cultivar he developed of several and apparently more are to come. I was thinking...

Donald, Since it's in your neighbourhood (broadly speaking), I thought I would mention a couple of Meilland 'La Sevillana' rose plantings in Vancouver. Along with 'Bonica', this cultivar seems to be a favourite rose to use for commercial landscaping in the city. Or perhaps just a favourite rose of o...

Re: cold-hardy breeders

Donald, In my opinion the best semi-hardy rose to use as a pistillate parent for a Zone 3 climate is 'Morden Centennial'. Very easy to work with and it can produce very good quality progeny. It's a mystery why it has produced only (if my memory is correct) one registered rose cultivar. 'George Vanco...

My favourite roses are Rugosas, since they are ideal to grow in a Zone 3 climate I have mostly lived in. I've grown many cultivars over the past few decades in several Canadian cold and warm geographical locations. This year I had a bumper crop of Rugosa seedling from my breeding work in 2016. Culti...
