Regarding shade, from my experience, Plaisanterie is quite shade tolerant.

I planted her where she could get maybe a few hours of late afternoon sun, but really it did not get even that, as clematis dropped on it halfway the season. Now I cut back the clematis and under it there she is, perfectly healthy, not even leggy 1 meter high and multi-cane bush (as she was about 10 cm high when I planted her it is nice achievement for a first year). Last summer she even bloomed and rebloomed, no disease whatsoever. The only thing that blooms did not have the orangy yellow coloration, but stayed violet-pinkish, not sure though if it was due to the shade, or due to the lack of heat in my climate.

Moving her to the sun this year, as huge clematis and huge thorny rose in one mess is something I rather would not have to deal with. :)
