I question the zone rating of 8a on this rose, considering its lineage and that it's grown in the region of Moscow, Russia.

The zone information came from the US Patent, which says,

"Cold hardiness: `POULbota` has been found to be resistant to damage from cold in USDA Zone 8 and USDA Zone 7."

Of course, since it is growing in a colder zone, the rose is probably hardier than reported in the patent.

I read that, Lyn, and wondered why it wasn't listed as 7 instead of 8. The I saw the Moscow pictures!! It must be pretty hardy, indeed. Thanks for the response.

You've asked a great question. I did change the zone down to 7.

My guess about the patent only mentioning hardiness to zone 7 is that the rose had not been tested in colder zones, so breeder did not want to make a disclosure that the rose was hardier than where it was tested.

Actually, I really don't know.

I don't know, either, but it sure looks like a great rose!

I know I'm very late to this discussion, but I just happened upon this rose tonight.

My reading of "resistant to cold damage" is that the rose has little to no Winter damage, i.e. is "green to the tips" come Spring. Here in zone 7a in central NJ, the roses that get no Winter damage would otherwise be rated as being hardy to far colder zones. I think gardeners consider a rose being "hardy enough to grow" means enough cane survives Winter to allow for having a reasonably-attractive plant during the following growing season. Here, even Bourbons and David Austins will have SOME cold damage, and they're listed as being hardy beyond zone 7. The only roses I have with NO cold damage are the OGRs with little or no China/Tea ancestry.

This is a vigorous, free-blooming, disease resistant climber in my garden. The blooms have a light fragrance and are long lasting.

I agree, it's very vigorous, individual blooms don't last long but they keep coming. No disease on mine so far either. Great rose. Strong but ethereal and delicate looking
