Wonderful!

15" or 15'?

Sorry, I just fixed it. 15 feet.

Blue Moon is a hybrid tea. This is very cold hardy (zone 4) so it can't be that. Sorry about the pictures. They are a true baby pink.

I thought it had a HT form, too, and was also wondering about the strong fragrance. I don't know much about true cold-climate roses, but would think that that this rose would climb in Zone 4 would narrow the field of possibilities quite a lot.

I wonder, is there any way to ask rose society members in the Adirondacks area? Someone somewhere must know. It really looks and sounds like a keeper!

No clue, but if you ever do find out (from Adirondacks rose society members?), I hope you post it here. Would the Syracuse Rose Society be nearby?

'Blue Moon' was one of the earliest "purple" hybrid tea rose varieties, released in the U.S. in 1965.

The lighter mauve color in your pictures is consistent with that variety. For comparison, here is a picture of some Blue Moon roses which are not in very good shape and look a little faded.

Blue Moon is only hardy to Z7b. This rose was found in Z4. Blue Moon, climbing form or not, wouldn't stand a chance in those winters, certainly not abandoned and unprotected. The OP also says the color in her photos is deceptive. It's actually "a true baby pink". Also, the found rose was living next the ruins of a cabin, so there's a possibility that it's much older than the 1978 introduction date of the climbing form, which this is (it is 15' tall). Though it resembles some pix of BM, I think we'll have to look elsewhere for an ID. I'm wondering if it might be an old Brownell rose? Or even Dr. W. Van Fleet, the sport parent of New Dawn and parent of many Brownell roses?

No. New Dawn wimps out abou 20 miles north of me. It wouldn' make it in the Adirondacks. Brownells aren't much better.

@mad_gallica (z5 Eastern NY) Welp, we're back to first base, lol.

EDIT: It would be so helpful to know if this rose is remontant, but I guess we'll never know unless it's ID'd through other means.

No, it only blooms once in the season. A late bloomer. It's full of buds right now. I will take more pictures when it does.

Take some good pictures of the leaves, canes, etc. That is what is going to help the ID.

Late bloomer might imply setigera in its parentage.

The color and vigor reminds me of a found rose from upper TN. Before you dismiss it as temperature limited, remember that in the 1980s we had a three day spell of temps in the minus teens and those days it never got up to zero F.

The found rose was growing under a collapsed barn.

I've also seen it growing in zone 4/5 over in North Carolina which means it might have been sold through the Biltmore catalog.

I think it was two lady names and named for the daughter of the Secretary of Agriculture (which would have been a very W Van Fleet thing to do).

I'll see if I can find the name somewhere, my plant was too tasty to the vole mole population in the good soil at the bottom of our hill.

"The found rose was growing under a collapsed barn."

Then it very likely could be a seedling from another rose (if it was growing in the area that was originally covered by the barn). That would make sense. (The original rose may not have survived all those years because it was growing on rootstock) Seedlings tend to pop up in partially shaded areas like near the edge of bushes or under a pile of collapsed wood, which can hold moisture in the summer and help protect the small plant.

Urn shaped buds, matte foliage, once bloomer? Strange. I don't see fused styles in the images but that usually breeds away after introduction of non-Synstylae lines. Honestly seems to have R. Chinensis DNA in it a little. Reminds me of those cold hardy Canadian hybrids

@stillanntn6b Ann, would that rose be Mary Wallace? It's not "TWO lady names, but she was the daughter of the Secretary of State, and had a climbing PINK rose named after her by Van Fleet, lol.

From Google:

Mary Wallace was the daughter of U.S. Secretary of Agriculture Henry C. Wallace, who served in the cabinets of Presidents Harding and Coolidge in the 1920s. In 1921, agricultural scientist Dr. Walter Van Fleet introduced the 'Mary Wallace' rose

Fascinating history!
