Very healthy, but stingy with the blooms.

Hi, Jonathan. Just wondering if your rose might have improved with the flowering (As a climber and a Kordes, I was thinking this might be a rose that requires a little time to put down roots.)

Rose Listing Omission

Rosa sterilis

A naturally occurring hybrid between R. longicuspis and R. roxburghii. Hips are empty and sold as fresh fruits for their vitamin C content.

Parentage is: R. longicuspis x R. roxburghii

Molecular evidence for hybridization origin of Rosa X sterilis ( Rosaceae)

Chromosomal-scale genomes of two Rosa species provide insights into genome evolution and ascorbate accumulation

Added, thank you! Have you seen any photos or description of the rose itself?

Most photos I've seen have come from the Texas A&M Rose Breeding and Genetics Program's Facebook page (link in my original comment).

I can't share the URL here, but Figure 1 from the paper below* shows the flower, habit, leaflet count, and distribution:
Single, light pink, 9 leaflets, dark green foliage, yellow/orange hips...

Discovered in 1983, endemic to the Guizhou Province, China. Hips have higher flavonoid content than those of R. roxburghii.

This just looks like a selection of Rosa carolina to me. I'm dubious of the claim that it is really a rugosa hybrid.

Bierkreek sells this rose as a virginiana hybrid, so perhaps it is a hybrid between virginiana and rugosa.
More pictures are on their website.

Or plausibly 2nd gen. Therese Bugnet.
