If you want repeat bloom go with Improved Blaze. My regular Blaze is a once bloomer in the spring. It should grow along a fence rail quiet well. It puts out very long and flexible canes that should be fairly easy to tie to the fence. HMF says that IB is available from Angel Gardens on line.

Not great fragrance but it should be hardy for you. I've never had any cane loss on mine over winter so you may get a little but otherwise it should do great!

I had a climbing Blaze rose for years. It only blooms on new growth, so you'll have to cover it in the winter in zone 5. Otherwise all growth will die from winter kill and only what's under the snow at the base will survive - so no blooms. I used to take the branches down and curl them on the ground then cover with burlap, anchor with rocks. I then piled all the cutback from the fall garden on top of that and they did fine. In the spring I'd uncover them and put them back up. That way they bloomed every year. However, if left up all winter, all branches died back and there was never any blooms. There are a few clmbing roses that are hardy enough to survive and bloom in zone 5 without being covered up, though.

I am in Zone 5 and have had Blaze for quite a few years. Have mine againt the house and used to wrap it and pull it down to the soil, then lay something on it to keep it down. It never got much winterkill. Actually had over 100 blooms on it one year. It finally cracked off at the base as it got older thu to being pulled down. I replaced it with improved blaze which I also pulled down but not as far last fall and laid a short but long wooden gate in front of it. Mine didn't get very much winterkill last winter either. Think being planted against the house is a big plus for it.
