If I ever get that way..... Agree with your favorites...I grow them all and they're all good here in Kansas. Champlain is everblooming, including one I have on the north side of the house almost in shade except for about 30 days around June to early July when the sun gets far enough north. It's also pretty blackspot resistant. I'd echo what you said about Morden Fireglow; my current one struggles and I've lost one before.

Use Helpmefind.com - it's THE rose authority on the net. You can do an advanced search for different groups of roses, for example you can look up just "Canadian Explorers" and just "ARS Pink or Pink Blend". Don't limit your search with parameters like height or bloom period, because a lot of their data doesn't include that so it would narrow it down too much. About half of the roses I personally posted are hybrid teas and not hardy like the Explorers and Mordens. Many of the beautiful hardier old roses such as the Alba group and some of the Gallica group are once-blooming which is something to consider, it might not excite everyone to have a month of blooms and then nothing. There are sooo many must-have roses for the Far North! I laugh when people ask for "just one rose" - not if we can help it!! LOL Here is a link that might be useful: Helpmefind Rose Search

In general, Buck roses aren't all that hardy. There are a few exceptions, like Applejack, but most are just crown hardy here. Disease resistance also isn't reliable. Hawkeye Belle had horrible problems with blackspot. Country Dancer is reasonably healthy, but less than 2 ft tall after about 7 years. Parkland roses are also problematic for blackspot. They are from a cold but dry prairie climate, and often struggle in the east. Morden Centennial was asked to leave at the same time as Hawkeye Belle, and for the same reason. Quadra is new last year, so it's hard to say what the final size and shape will be. Get it grafted. It doesn't seem to want to grow own-root. Seafoam looks to grow about 6 ft canes. Whether that is long enough for what you want, I don't know. The trick with the new trellis is going to be finding a rose the right size. A monster will eat the gate, a wimp won't do much of anything. My Quadra is in a similar situation, and I'm hoping it doesn't outgrow the spot. Captain Samuel Holland is exactly the right rose, but it's down the row a bit and I don't feel like moving it. John Davis is another possibility, and maybe Clair Matin.

Below is the info. that Floweraremusic (zone 5) in Washington gave on her 2020 winter-survival. She has alkaline clay with rocks at bottom like mine & less snow in winter: "My hardiest roses are the Canadians. John Davis, John Cabot, Wm. Baffin, Morden Sunrise, Morden Blush and Morden Centennial, Victorian Memory aka Isabelle Skinner, also a Canadian rose. All these only have tiny bit of tip damage and bloom a lot with no special care. Also, my Hybrid Perpetuals only have tip damage after winter. Magna Charta, Mrs. John Laing, Black Prince and Marchesa Buccella. The only negative is they don’t have long enough cutting stems. All my Austins are very hardy. The one I just can not grow is Jude. Leonardo da Vinci is super hardy and always healthy. Quietness comes through winter very well. Even Rouge Royale survives beautifully. Cinderella Fairy Tale is very hardy. Gruss an Aachen also. Ballerina and Marjorie Fair are both hardy. Poseidon, Princess Charlene de Monaco and Crazy Love didn’t do as well as I’d hoped. The surprise losses this year are Quicksilver, and Dames de Chenonceau who is left with only 1 cane. Versigny is also reduced down to almost nothing. This was a mild winter with very little snow. " Floweraremusic (zone 5). From StrawChicago (zone 5a with hard black-gumbo alkaline clay & less snow but with freezing rain in winter). Versigny didn't survive winter either.
