I agree, I’ve been looking for Moore’s roses in Europe for a while and they are pretty much impossible to find.
Exceptions:
Yellow Dagmar, Paintbrush and Sweet Chariot (sold as Insolite) available from Loubert.
The ones Roseus mentioned above, Mr Bluebird and Dresden Doll, available from Lens.
I also found Red Fairy and Lollipop on the Pharmarosa website, but I don’t know if they’re the real deal. I ordered Baby Darling from them thinking it was the Moore one and it is definitely NOT the real one so buyer beware.
Edit: To make things more confusing, some varieties have the same name as Moore roses. For example the Golden Angel that is often found is the Poulsen one (POUlpal056), and the Red Cascade that can be found is the Delbard one (DELtapirou)…
I’ve acquired Dresden Doll in november with Topaz Jewel (Yellow Dagmar). Not many other Moore roses available. Maybe Scarlet Moss also. As for yellow miniatures. Baby Love would a good one. She has a vast amount of offspring. Gives good resistance.
As for more Moore’s roses in Europe. Maybe accidentally cut off some budding material in a rose garden. 
Pharmaroses looks very shady. They’ve more than one site. All look the same. Stumbled upon the a few times when searching roses.
@KarelBvn I ordered from Pharmarosa this summer. Aside from the Baby Darling that wasn’t one, the other two were legit (Evelyn and Berlingot), and the order arrived fast, even though the roses were quite small (which was not a surprise, 2 liter pots) they have taken off well.
“As for more Moore’s roses in Europe. Maybe accidentally cut off some budding material in a rose garden. ” That seems to be the only way indeed, IF you can even find them growing somewhere!
Good to know they’re ligit. Because they do have roses you can’t find elsewhere. They have sites in a lot of languages with they’re own URL. Pharmarosa.nl for instance would make you feel you’re ordering from a Dutch company, but the (automated?) translation is sometimes weird. I’d rather they just used one domain and be clear about their location. It appears to be a Hungarian company located in Budapest.
They’ve a nice selection of Geschwinds roses of course 
This is a selection of Moore’s roses I found to be present in my region, as for now.
- Red Moss Rambler
- Eleanor
- Lollipop
- Little Flirt
- Dresden Doll
- Little Buckaroo
- Mr. Bluebird
- Topaz Jewel
I’m afraid we wandered off-topic a bit.
Apricot Twist appears to function as if it’s a fertile triploid. Golden Angel, its seed parent, seems to be a strong breeder of fertile triploids. Crossed with the tetraploid, Orangeade, it produced the fertile triploid Torch of Liberty. That, crossed with the tetraploid Basye’s Legacy, produced the highly fertile triploid, Lynnie. Fertile triploids seem to be a strong line the rose wants to follow.
One rose I’m looking at to cross with Rugosa is Gold Coin. A yellow Moore miniature that’s been found to be diploid. It’s available from Garden Roses in the UK
Another possible source of yellow is Malvern Hills, also diploid, and available from a number of EU countries
My thought is to pollinate these two with Topaz Jewel to inject some Rugosa into the offspring, then select the best yellows with visible Rugosa traits to cross into pure Rugosa. My hope being that the Rugosa genes in those seedlings will result in better fertility in the back cross to the species.
I’ve tried crossing Topaz Jewel with other Rugosa but only got pink shades out of it. So do think finding another source of yellow is probably best. And for my money those two are the most likely option
Another possibility might be Broadlands which is also pretty widely available in Europe. It’s not confirmed as diploid but I did some pollen diameter measurements on it a while ago that sit within what’s expected for a diploid. Things went a bit south for a while before I actually got around to using it, but it still seems to be worth a try
I’d be interested to see how you get along with them if you try them yourself. Sounds like we have similar aims
I’ve got two crosses with Topaz Jewel this year, still in fridge. It isn’t very fertile as a father. Haven’t tried her as a mother yet, new plant, too young. But i think it probably isn’t suitable as a mother.
For the crosses this year I’ve pollinated with TJ on over 49 flowers and 18 flowers on two different diploid roses. I’ve only got 3 and 2 hips out of them. These roses I put TJ on are very good mothers with 80+ and 90+% hipset with 20+ to 40+ flowers pollinated. Hipset of TJ is 7.4%, depressingly low.
So no high hopes. But you only need one lucky shot. 
I did okay with it as a pollen parent. Zero hip set for me. But pollen wasn’t too bad. It actually took on Thérèse Bugnet which was really unwilling to set seed with every other pollen I used on it. I have a page on HMF with a few of the seedlings from that cross on it. Nothing unique enough to do much with came from it. But they weren’t horrible roses. This is the page if you’re interested in seeing them: 'Thérèse Bugnet X Topaz Jewel
As you say, you only need one lucky shot. I didn’t manage to get one. But no reason why you couldn’t get lucky.
At this point I’m looking at TJ as a way of inoculating seedlings with a little Rugosa before crossing those seedlings back into more pure Rugosa. Planing to use it on yellow diploids and triploids to try and get some part Rugosa yellow seedlings for the job. Hoping that proves a more productive route for me
Ironically, the only result Mr. Moore obtained using Topaz Jewel he retained was Peach Candy and that was from using Sheri Anne, which is available from Pocock. It’s tetraploid but worth trying. It had nearly become extinct here. Fortunately, Carolyn Supinger who basically ran Sequoia Nursery for decades remembered it was in the Ralph Moore Memorial Garden there in Visalia and sent Paul Barden cuttings. He sent me a photo of it flowering for him today. It’s a worthwhile mini for breeding.
I got Topaz Jewel last year in hopes of setting hips on my setigera serena with it. (Of course TJ promptly died when the Texas death star fried it, and my dumb setigera has yet to bloom at this property. Methinks most roses really aren’t remotely xeric.)
I wonder if Geschwind’s hybrids between setigeras and rugosa’s were accurately reported. Any thoughts on that hypothetical cross? I love the concept, but don’t want to make any unnecessary sacrifices to the garden gods. (I hadn’t realized TJ was poor parent before reading Paul’s balloon-popping post above, though I suspected it might not love it here in TX. (Neither do I, really.))
Would Rugelda be better, and still be diploid?
I’ve acquired Rugelda this year, still in the earth waiting for me to cram it in somewhere. There’s always room for one more rose
I’ve got my hopes on Rugelda for introducing Rugosa into other rose families. I think she’s the best rose - on paper - with Rugosa parentage to experiment with. Kordes creates really tough roses, I wouldn’t be surprised if she holds off your Texas death star . Kordes used her in several other roses that are still in their current collection and are doing well.
She very well could be diploid or maybe triploid. My first guess was tetraploid pure based on her appearance. Looking at her parentage, it could be anything :). For Kordes she worked well as a pollen parent.
Keep me posted on your results regarding this rose, I’ll do the same. Best of luck!
Here in the Mid-Atlantic, Rugelda was heavily infected with blackspot. I would definitely mate it with roses having better disease resistance, if I chose to use it in breeding at all (but then, without better disease resistance, I’m not certain if there is much reason to use it). Its parent Robusta was diseased for me even in the warm, humid summers of the Upper Midwest and also insufficiently cane-hardy in winter.

Ow. That’s disappointing to hear. I’ll see what it does here in Belgium. We’ve got our share of humid and rainy days… I’ll do some back crosses with strong Rugosas and go from there.
I’ve tried the pollen of this one on a few roses I thought would match, but didn’t get any hip. This year was a good year for hips here, but still… Not much pollen on Robusta. The pollen also dried up very quickly and rendered useless. Schneezwerg, Thérèse Bugnet, Topaz Jewel, Robusta, … They’re all very hard to match. Rugosa isn’t the easy road to choose. That is a certainty.
Both Rugelda and Robusta may still be perfectly reasonable varieties to grow and use in breeding for both cooler-summer and drier climates. Here, humidity comes with quite a bit of heat, and summer days and nights for several months (with hardly any interruption) tend to be hot and humid–right in the temperature range favored by blackspot. Some rugosa hybrids stay very healthy here while others struggle. Most of them still have major trouble with cane borers, with various sections dying suddenly for much of the post-bloom growing season as a result. It doesn’t make for a very attractive garden plant when that happens, although it’s even worse when large ramblers suddenly lose large growths many feet up in a tree.
I haven’t tried growing Topaz Jewel in my current climate, but it would be interesting to see how it does here. Where I used to live, it was pretty healthy, but it had very inconsistent cane survival in winter (the odd cane stem might come through reasonably well, while most others would be reduced to almost nothing, without any clear patterns related to age or health or size–this happened to some degree with certain other rugosa hybrids, too). This resulted in a rather awkward-looking plant, and if it’s as soft-wooded as I remember, I would bet that it will also be cane borer candy. It would ideally be possible to cross it with another warm-colored rugosa hybrid so that cold hardiness isn’t diluted further. Trying to diminish the abundant prickles through such a cross would probably be asking a bit too much, though…
Here in Coastal z7b on Vancouver Island, I’ve grown Rugelda (on its own roots) in a pot for several (10?) years and without fail OR SPRAYING it remains one of my cleanest foliages among all my roses.
