I will be interested to read what suggestions others offer.

You might want to check the High Country Roses website. You can search by hardiness zone there, and they have a lot of cold hardy roses. The cultivars include both modern and heirloom roses.

The obvious answer would be some Portlands. I can highly recommend 'Comte de Chambord' (better repeat than Austins, here, and great scent, hardiness, and tidy habit) and "Rose de Rescht" (almost as good as CdC, though with a slight tendency to damask crud).

@Rosefolly z5 - I think High Country Roses is great. I had not used the filters in the past and so thanks for informing me they were there. I do wish they sold larger plants. my growing season is so short - about 3 true weeks of summer and 60 frost free days - it seems it takes the roses a year or two extra to reach the same point compared to my previous garden.

@Ross 5b IA - I have CdC and love it. Is RdR cane hardy for you or at least preserves a lot of its canes? I was nervous about getting RdR because I heard it was not as hardy as other portlands. Although my area was recently changed from zone 4b to 5b, we still very much have zone 4 temperatures each winter.

"Rose de Rescht" is cane-hardy here: it has survived four winters with no trouble. (Far hardier than my 'La Reine' -- RIP.) It will sucker somewhat, so you can slowly increase your stock of plants. I haven't noticed that it's any less hardy than other Portlands (or early HPs) I've grown.

Speaking of which: I should also probably recommend 'Marchesa Boccella' and 'Yolande d'Aragon'. Neither has been quite as successful for me as CdC and RdR, but then, they're in much less forgiving spots in my garden.

Oh, and one rather different recommendation: 'Gruss an Aachen' may be worth a shot, in a protected part of your garden. It too has survived four winters here, and though sometimes it will die back nearly to the ground, it always rallies and puts on a great show of bloom. Very compact habit -- a sweet little rose, for the right spot.

@Ross 5b IA - that’s awesome - I’ll plan on getting Rose de Rescht then. I grew it in my last garden but had only had it 2 years when I had to leave it behind. I planted Marchesa Boccella last year and it grew vigorously. I had to prune it close to the ground this year but I’m hopeful it’ll bounce back well.

I’ll have to consider getting Yolande d’Aragon in the future again. I grew it for years in my last garden and loved those amazing blooms but was an ugly, disease ridden plant that I put up with. Thankfully there is very little disease pressure where I live now. That’s great to know about Gruss, too - another I wouldn’t mind trying.
