Polemonium brandegei

I find I have propagated several Polemonium brandegei, and I can find very little info on them. If they require a hot dry climate, they will be vastly disappointed here in South Central Alaska. They are in my unheated greenhouse, at the moment, and doing fine. Does anyone have any info on this fellow?

Hi.. Have you tried Polemonium brandegeei on Google..Here http://www.robsplants.com/plants/PolemBrand.php it is listed as Z 4 - 8 perennial. Just trying to help...

Thanks so much, Saya. I Googled, but missed that one. I really appreciate the help. This one may be able to winter over here. I guess it depends on how it likes our wet autumn and spring! Thanks again.
