Also, this is as far as the blooms open, they stay cupped.

I have no idea, but would like to know as it's very charming. Does it have many thorns.... fragrance?If you don't get a reply, perhaps try cross-posting to both the Antique and Rose forum.

The main stems have a few thorns and humps that were thorns but the side shoots have more--kind of like kitten claws, tiny and sharp but as they grow out some of thorns become little humps and lose their points. No fragrance. It is a slender stemmed bush with a lot of side branches and covered with flowers and they kind of dance in the breeze.

Hmm. I wonder if it's The Fairy. I have a tiny cutting, but it can get fairly large. Mine seems more double. https://www.helpmefind.com/rose/l.php?l=21.280727

It isn't as dark of a pink and the petals are kind of ruffled/cupped.
