Zone 4 is difficult... (is it the North Pole?) Anyway, in my milder climate, Kordes roses worked well for me. Maybe with some protection: 1) Dortmund: Individual flowers may not be extremely handsome, but the entire effect is impressive. 2) Rosarium Uetersen: although not really red (but rather a dark pink, or "coral red") it is a beauty! (These two come with the added bonus of being disease resistant as well). This post was edited by mikeber on Mon, Apr 15, 13 at 22:53

Rev d'Or did very well in Earthkind trials for Texas gardens, so may do well for you, too. I like a modern red climber in my garden - Dublin Bay. It reblooms well - no fragrance, though. It can definitely take the heat. Anita

They had a pink climbing rose at Lowes but forget the name of it. Would have got one but they looked pretty pathetic. I looked on the tag of the 2nd one said it was grown in Canada but it didn't have the name of "Demokracie" anywhere on the tag that was tied with string around the main branch of it. So I imagine like the first one it is the Original blaze. It is doing so awesome the first one. Here is a picture of it. And I found out I can plant the 2nd one I got up against the Wooden Fence like this one only further down. YAY!! Discovered caterpillar or rose slugs not sure which on it anyhow I picked them off and threw them over the fence :) Was on just one branch as you could tell by the leaves. I also removed two that had the leaves like a cocoon with the caterpillar in it so just removed that entire leaf bract and pitched it over the fence. Haven't seen any since on it. I didn't want to spray it as we do have chickadees and chipping sparrows come to our gardens too. Have set up a small birdhouse in it and the chickadee have taken up residence it . They are sooooooo cute.

I am trying a vintage rambler (1961) called ILLUSION this year. It is a lovely, vibrant red. Available thru Vintage Gardens. I'm trying other old roses through them as well. Some like CECILE BRUNNER and the David Austin CONSTANCE SPRY are said to make nice climbers or you can prune them to keep them as shrubs. I had horrible luck with hybrid tea climbers because they usually bloom on old wood and mine die back to the ground every year. Because of the Indian Summer last year I had flowers last fall on my climbing Peace. I think it has flowered 2 or 3 times in 12 yrs....it needs a new home. I've had wonderful luck with old, own-root climbers. I have a DOROTHY PERKINS (small pink clusters) that has nearly eaten a porch it got so big. No fragrance and no rebloom on that one. Very little die back at all. I also have one that was a cutting from my grandmother's. I think we've identified it as MARY LOVETT. This one is white with yellow buds, tea like, sweet fragrance and does rebloom. Moderate die back each year but it really does well on the bloom. Another oldie that I received in a trade last year is New Dawn. It is a soft, pastel pink and occasional rebloomer. My very small cutting survived the winter with minimal mulch and not a bit of it died back. You can look these and other roses up on the Rose HelpMeFind website.
