Roses sure do well for you. I have restricted myself to the hardiest types of roses. I just don't have time to prepare the tender ones for winter anymore. This spring I had a lot of cane die back, and then the little wasp larvae did their evil on them, before I got to the spray. I sure am appreciating the ones that are blooming now. Most of them were a bit later this year. Do you have Banshee? I could send you a nice sucker of that one. Blooms on old wood.
I don't know about Banshee always being winter hardy in Calgary. It is a beautiful pink rose, but needs a bit of room. Would be great at your farm. I didn't get any bloom this year because the canes all died back to the ground. We had a winter that took a lot of perennials and a lot of things were very late showing up.
I have bought roses from Sheila Holmes at Rocky Mountain house. She sells Robert Erskine roses and a few others that he grew and liked. Some of these bloom on last years canes. If they can grow them there, you should be able to grow them and have them bloom most years. I think Banshee is about as hardy as most of those. I bought it in Morden and I know other people that grow it in Manitoba.
Black Bacarra is one I would sure love in my garden. Will have to just enjoy it through your photos.
I find that mounding peat moss about 8 - 12" works best. You will find the canes will stay green under the peat moss. In the spring, when the days start getting warm and temps are consistently warmer than -10ºC, start pulling the peat moss off in stages. Otherwise you will get weak shoots under the peatmoss since it really heats up.
Get a load out of this. Very weird. My Gertrude Jekyll is now 8 feet tall and has bloom continuous all summer. I had to measure it since it has never gone past 4 feet in six years. Also in past years it would have the 1st big flush of blooms and hardly anything after that flush.
