Does this rose set hips? I'm pretty sure it's triploid, but it clearly has a ton of descendents. Probably through pollen? A lot of bourbons are triploid, but I'm sure most of them are at least slightly fertile crossed to tets.

IF the parentage is true, it is likely triploid. Regardless, many fertile triploids exist. Some more so than others.
At least one of its descendents should also triploid, or diploid, though.

Does anyone have this rose available in the states? Has anyone else attempted this kind of cross?
I think Therese Bugnet x Muriel or something to that effect could be a really interesting territory for creating good thornless reblooming bracteata/rugosa/species types.
Or Pink Surprise x Therese Bugnet could really double down on the rugosa genetics, and carry bracteata lineage while still being thornless and reblooming. A lot of seeds would have to be grown to get the right outcome.
Is Pearl Drift really a Mermaid descendant? That could be another inlet for bracteata genes.
I love the concept of taking all of the naturally remontant species and crossing them at nearly pure strength to create a new rose class that combines the natural vigor of species and introduces new remontancy genetics.
Some of the better remontant species:
Chinensis
Rugosa
Bracteata
Clinophylla
Wichuriana
Fedtschenkoana
Moschata
Beggeriana
Some of these crosses exist. Kordesii is wichuriana x rugosa.
Damascena is (gallica x moschata) x fedtschenkoana
Rugosa x chinensis exists, but their remontancies don't match up very well. For some reason, Hybrid Perpetuals or Hybrid Tea crosses seem to work though.
Rugosa x bracteata exists. They seem to be good at repeating but not necessarily abundantly blooming.
It will probably take good selection of parents and careful planning to cross these hybrids at the correct ratios.
I think a lot of great things would come from crossing the oldest healthy lines of roses back to exotic species, then crossing with a modern HT.
(Portlandica x rugosa) x HT
(Damascena x Kordesii) x HT
(Hybrid Perpetual x bracteata) X HT
As usual, I have rambled my way off the page!
Anyway, if anyone is actively working on these kinds of crosses, let me know. I am even better at reading than writing, and that's saying a lot!

I have Frau Dagmar Hastrup x Bracteata seedlings at the moment, about a year old. While the pics by Robert of this rose seem low thorn my seedlings seem to be mostly like bracteata with foilage half way between the parents and lot more thorns. Just hoping the lower size of Dagmar wins out in some of them as that would be an improvement over bracteata.

Sorry, this rose has vicious prickles and bristles. It's dauntingly vigorous.
I managed some hips using the pollen a few seasons ago but rodents got to them.
It blooms a bit late here and at the top of of tall canes.
It's not easy to use.
I don't know if Tom got anything out of it or not.

That's a bit of a relief, that my results aren't just worst case scenario. Something to run through smooth rugosa hybrids when mature either way.
Tom mentions on his blog that he had OP from one of the four bracteata x (rugosa x palustris)

I have read that this rose is sterile. Is it even sterile as a pollen parent?

Apparently not. Peter Harris used it on 'Golden Showers'. He got a raggedy, pale yellow bloom on a plant with some blackspot.

It's the only rose I've grown that got rust. I wouldn't bother to try breeding from it!

I can't dispute that. I last saw 'Agnes' 40-odd years ago. I don't recall any rust, but that was in Kansas and the clearest memory I have is of the fragrance. Nice color, too. Come to think of it, I don't recall any rust at all in the Reinisch Rose Garden in Topeka.

No rust on Agnes in my cool acid soil either.

Several websites claim this rose is remontant. Supposedly, it not only reblooms, but abundantly so. Is that just a line to sell plants, or does this rose really rebloom?

Palustris 'scandens' repeats and could be hybrid in origin. The true species does not that I'm aware.

I have never seen the wild R. Palustris on Cape Cod rebloom although the bloom period can last several weeks.

Wow. Palustris itself answered. Lol. Hi palustris, do you rebloom? hehe.
I think it's the Antique Rose Emporium that sells the "reblooming swamp rose" and I think RVR has it too. They list it as "rrrr," as in very remontant. I think I'll get one at some point. Just wondered if anyone had any experience with it.

Most wild types in Florida are once-flowering. But we grow one I collected in the wild (several photos of it here) in the Green Swamp, Sumter County Florida, probably 30 years ago. It is absolutely continuous-flowering. And not just a flower here and there in the heat of summer -- LOTS of flowers all the time. Some nurseries (especially Florida nurseries) are growing our clone, so in that case, they are telling the truth. My photos here on HMF that say that it is growing at Florida Southern College are all of that clone.

Malcolm,
Thanks for the excellent photos.
I have to wonder how cold hardy your form will be.
Thanks, Robert
