I do hope someone can help with an ID. I'd love a cutting, but who knows about customs.

I somehow recognize this from researching what polys to get this Spring. Perhaps you could search polys in helpmefind.com. I might also try posting this to the Antique Rose Forum. It doesn't seem like this one sees much activity. If you get an answer there, please copy it here.

I also asked the question on the ''Name That Plant'' forum wich has more traffic and answers: https://www.houzz.com/discussions/id-this-plant-please-pink-flowers-dsvw-vd~4162833

I'll have to check that. The antique rose forum Id'ed my unknown poly in about 5 minutes. I was awed.

Oh, you got good answers there. I think it's DickK. That's why I thought I recognized it; I have Margot Koster. I can't imagine Montreal is zone 5. I lived there for 7+ years and it was practically arctic, although somewhat warmer than Quebec City. Much colder than the Albany area. You're lucky to live there; I miss it so much.

Well with climate change things are not the same year in year out. Last winter we had a lot of days above 30F and without any snow accumulation. While in New York, they had multiple snow storms (the one we are used to experience in Montreal). In addition the polar vortex did affect the US down to Florida last winter. But in Montreal we didn't feel any of its effects. It was almost a summer destination.
