According to the Catalogue of Life web site (as of August 2021), this species is a synonym of R. davurica.

This rose is rated hardy to zone 2b in the following paper:

Roses for the North
Performance of Shrub and Old Garden Roses at the Minnesota Landscape Arboretum
Kathy Zuzek, Marcia Richards, Steve McNamara and Harold Pellett

Minnesota Agricultural Experiment Station University of Minnesota Minnesota Report 237-1995

Could there be a change made to the current hardiness rating? Thank you.

Hi Rob,
Further to your reference regarding zone 2, we know Georges Bugnet was using R. amblyotis in zone 2 Alberta (1930's), Canada when he developed his famous rose 'Thérèse Bugnet'.

Hello Margit,

Thank you for your reply. I learned about R. amblyotis while looking at 'Therese Bugnet' lineage. R. amblyotis was listed as being hardy to zone 6 and thought that couldn't be acurate. So I did a little searching and found the reference I posted.

I have changed the hardiness rating to 2b.
Rob, if you have posted references, and I know you are familiar with adding your own roses, could you have changed this hardiness rating yourself? HelpMeFind always needs more volunteer administrators.

Patricia, I don’t believe that I have the ability to change any listing other than my own or ones that I’ve added on behalf of someone else. I’d welcome the ability to volunteer. Thank you.

One can easily see, from whom Thérèse Bugnet got the typical flower bud-form!
...And it's purplish red stems.
