Sorry I missed your post - I was off rose forums for a while after losing all my roses to RRD in 2022.
I have had reasonable luck overwintering Comtesse de Segur but it stayed pretty small for me. I've gotten better results lately by growing on roses in pots with plenty of water before planting them in the ground, so I'll probably replace it.
Far better for me though is Dames de Chenonceau. My word, that is a lovely rose! It cascades across a low fence putting to shame the height estimate of 32" on hmf. I'd say mine is a loosely draping 6-8 feet. It blooms all summer and can be breathtaking. It's also cane hardy and tough as nails. After losing everything to RRD, I had to be extra cruel and spray roundup on any stray sprouts throughout 2022 and 2023 to make sure they weren't harboring RRD that would resurface. Wouldn't you know it, Dames de Chenonceau survived being sprayed with roundup at least 6 times over that period and has still survived (no RRD btw). It's a tough cookie and just gorgeous!
