I was sorting through some plants I overwintered and propagated with the desire to share with others and here they are:
L83- Ag Canada germplasm release (direct parent of many Ag Canada roses and grandparent of others- Marie Victorin, George Vancouver, William Booth, Louis Jolliet, grandparent of Cape Diamond, etc.)
Yellow Altaica
Hazeldean
Prairie Peace
3K20 (Max Graf x likely John Davis)- tetraploid and fertile spring bloom, but has some repeat offspring, very healthy and climbing.
Some are own root, others are from stents (grafting and rooting a cutting at the same time)
Please use the link to email me privately if you would like something and provide the address you would like them sent to. There aren’t that many of each, so hopefully I can get you what you want.
Take Care,
David
May I postulate for Prairie Peace and eventually Hazeldean.

Yellow altai, Hazeldean and Prairie Peace are nearly impossible to propagate. Can you tell us more about your process? Which method was most successful?
Thanks
Hi Margit!!
I took a section of stem with two leaves on it (cutting back some extra leaflets if needed to allow them to fit) and did a whip and tongue graft onto a Dr. Buck thornless multiflora stem section where I deyed it to help reduce rootstock sprouting. I use parafilm to wrap around the graft and then put rooting powder on the rootstock cutting section and pot them up and put them under lights. I use a perlite peat mix (75% perlite) and put the whole tray in a clear plastic bag. I use plastic straws to help keep the plastic elevated. It seems like the straight cuttings I potted up at the same time of these challenging to root roses seem to brown at the base and fall apart. I think healing with the multiflora helps somehow to keep it from going downhill rather than having that cut end try to produce roots. The leaves photosynthesize and seems to help fuel the healing of the graft. I think in the long run planting deeply and trying to have things go own root would be something possible- kind of like what people do to graft tree peony scions on herbaceous rootstocks and then hope they go own root.
Take Care,
David
