Mike, I can’t tell you what the J6 bush looks like. But note it has ‘Austrian Copper’ in its pedigree, so it might be quite upright in form.
Reviewing the pedigree of ‘Morden Sunrise’, which is a complex one of several pinks, reds and yellows, it’s obvious its progeny will also have a wide range of colours. Depending on the staminate parent, the range could even be wider. So the breeder should keep that in mind when working with it. Of course, one could say that with most modern shrub rose cultivars. Except in this case, there is the relatively late addition of three species (Rosa arkansana, Rosa foetida and Rosa spinosissima altaica) that I think would make breeding efforts with this cultivar more complex. That is, it would take take the development of more seedlings than average to obtain the goal the breeder wants in a program. Just speculating.
Paul, can you give any information on where to find a reliable pedigree for ‘Morden Sunrise’? The Canadian Rose Society page says, “Morden Sunrise is a complex hybrid that incorporates Rosa arkansana, Assiniboine, Sunsprite, White Bouquet, Fire King and Prairie Princess” and makes no mention of any contribution from J5 or ‘Hazeldean’.
Stefan, check the ‘Morden Sunrise’ post on the Forum. I provided the pedigree, and since the information came from Morden it is accurate. For more details of the pedigree, it is found in HortScience 2002, Vol. 37, No.2, p. 410 - 411.
Paul, if you can find that HortScience announcement re. Morden Sunrise, it would be nice to post the ancestry of each of the various parents in a form that could be used to update HelpMeFind’s database. Specifically, we would need the parents of each contributing parent, grandparent, etc, listed in the usual Rose x Rose format, just as you have done for the immediate seed and pollen parents of Morden Sunrise.

In case someone is interested, my cuttings of J5 came from Paul Zimmerman at Ashdown Roses. He still has the plant and may be willing to send cuttings.
A few of you have emailed me to ask about J-5. I got it from Mike Lowe who got it as a test rose from Canada. I’ll be happy to share cuttings but our of respect for the breeders let me contact Canada first to make sure it is okay for them. I’ll ask if I can share cuttings with members of the RHA with the understanding they will use it for breeding only.
Is this okay with everyone?
Of course, their wishes should always come first. I wonder if it would never be officially released as a cultivar because it only blooms once - that would be a shame, because it looks like one incredibly beautiful rose.
I dunno, Golden Chersonese is only once-blooming and I thought about buying it. If it was released, places like Forest Farms could sell it since they sell once-bloomers as specialty products–and other nurseries, too, obviously.
That works for me Paul, Thanks.
I doubt J5 will ever be named. There was some thought about doing so, but since it is a once blooming Spinosissima it didn’t fit in with the Parkland Rosa arkansana hybrids developed as bedding roses for the nursery trade. These cultivars also have to be relatively easy to propagate by soft wood cuttings. In this respect, my experience with J5 is that it is more difficult to do so. No question that it is a stunning rose in full bloom and one of my favourites. It should be used more in breeding programs for developing yellow bi-colours.
