rambling about foliolosa:
My foliolosa came from somewhere like High Country. It was a light pink and didn’t seem to have any tendency towards dark purples like Paul’s did. As a late blooming species rose that set hips easily with any pollen, I used it more than I should have. It was blooming at a time of year when I was less busy and had more time to pollinate. Mine had the unusual ability to create the occasional reblooming seedling.
I’m speaking in past tense because it grew up with quackgrass and I dug it out.
Most of my many seedlings of foliolosa were unspectacular and have been dug out. Many suckered like a finch. However a finch suckers.
The Will Alderman x foliolosa seedling in this thread looks pretty healthy and vigorous and it reblooms. I might use that if it builds itself up into a healthy everblooming shrub. I also have a R. foliolosa x Commander Gillette which is pretty nice and seems to rebloom. That is likely a triploid that is 2/3 Commander Gillette.
“And how, exactly, does a witch sucker? LOL”
Very aggressively, Philip! LOL!
“If its thornless, it doesn’t sound so bad. Wonder what it would do mixed with fedtschenkoana-lines, foliage-wise. Have you crossed R.f. with anything mauvey?”
Yes! IHTXLB X Fedtschenkoana is on HMF. 'IHTXLB Fed' Rose
“If you are offering, I might just take you up on that. I’m assuming it would tolerate my new yard. Can I send you some TX treats in exchange?”
Once I get it started in multiple pots, one is yours! Thanks for the offer, but I’m honestly to the state of having to cull something to make room for anything new coming in. I actually found a climbing Brilliant Pink Iceberg at Home Depot today and wanted it…but there is no where to even hold it until it might be planted. A REAL climbing Brilliant Pink Iceberg! It has to be gorgeous planted!
“Saw your other post about R. spithamea too, Kim. That is a totally new one on me. Do you have to burn down your garden to get it to bloom?
Fun stuff.”
The pot isn’t melted and it’s flowering, so…
“Yes! IHTXLB X Fedtschenkoana”
Okay, now THAT is one interesting mash-up! LOL. I’m keeping my fingers crossed that the lottery numbers align on all the potential genes in there!
I reckon Texas treats don’t have to be garden related! 
As far as you know, has anyone every crossed anything with spithamea? (In researching it, I also came across your native Pine rose. Lovely red on that one, but seems pretty particular about cultivation, and I would presume pretty useless for breeding?)
Well, there ARE self seeds of the IHTXLB X FED available if you would like them and there ARE self SEEDLINGS of it which are HUGE in only ten months, which I have NO room to grow…(hint, hint). It appears Spithamea and Bridgesii are closely related. Mr. Moore created Golden Angel X R. Californica “nana”, which may well have been Bridgesii, so… Hopefully there will be hybrids between this and the 1-72-1 pollen I’ve already used on it and its pollen I’m drying to put on other seed parents. I also have dried Tom Thumb and Paul Barden’s 81-02-09 to put on it.
