It does not seem possible that this is a zone 6b. It is listed as very hardy and was bred at the Swedish Agricultural University. Is it really 6b?

Probably not. Ulrika Carlsson-Nilsson's other three roses are listed as 2b through to 8b ('Irma'), 3b and 4b. As they all used the same pollen parent of 'L83', I would imagine they should all be listed with the same zone. However, my weakness is zones - I just don't know 'em. Can someone confirm that they should all be listed ....3b and warmer?

If I could get my hands on one, I would be happy to test it in nominal zone 5a... which seems to become 4 if we do not have much snow cover!

They grow, according to the Gardens tab, in Rosenlunds Rosarium, a public gardens in Jönköping, Sweden. This appears to be in zone 6b, assuming that the European zones correspond to US zones. I am very surprised to find that Sweden tends to have warmer zones than does Maine, where I live. Of course, this does not tell use whether the rose will only grow in this zone. The Swedish Agricultural University seems to have major branches in Alnarp (close to Malmo which is 8a), Skara (7a?), Umeå (5b) and Uppsala (7a).

This rose, 'Balder', is very hardy and can be grown in the very North parts of Sweden.
This means zone 6 = Swedish zones!
I don't know what that is in US zones, sorry

Thank you Elizabeth and Christina. Nilssen's four roses changed to 6b and warmer.

According to a new rose testing project in Sweden (http://www.rosensdag.se/) all of Nilsson's roses are consired reliably hardy in swedish zone 5, encompassing localities which range from Usda Zone 4a - 7a. They also make bushes so it means that they are cane hardy in those zones. Balder is/was rated since before to swedish zone 6 according to Nilsson and is considered the hardiest of them, testing occurred during the 90's. I don't have info on the testing locality in swedish zone 6 from the 90's nor could I find any, therefore the Usda Zone for this particular swedish zone 6 growing locality cannot be confirmed.
