So sorry about that mishap, Masha. I hope your rose grows back quickly. Aimee, I have Bermuda's Kathleen and I can attest to the fact that it does well in the heat, since it's planted in full sun in front of a heat-radiating large boulder. Then it was half-buried by squirrels who were excavating under the said boulder and dumped all the dirt under the rose. In spite of that it's still blooming and putting out new shoots. It's not at its most attractive now and under these conditions but it was lovely last year and seems to be in constant bloom. I haven't grown the other two and can't make a comparison. Actually, I just remembered that I grew Archduke Charles years ago and for me it was mostly a very dark pink without the lighter coloration. It must have been the heat. Ingrid

Princess Charlene is over 10 feet tall right now 9/14/22 in my zone 5a. It's a 4th-year own root. Carding Mill is 2.5' x 2' right now as 11th-year own root. Carding Mill has bush beauty, Princess Charlene does not .. looks very odd with a super tall cane in the middle. Carding Mill always have zillion petals, Princess Charlene has less petals (single or double) in hot summer. Carding Mill loves hot & dry over 90 F. Since it's a small bush, it doesn't demand tons of water and fertilizer like other Austins that throw 4' octopus canes. Carding Mill does best in hot & dry & alkaline region. Its color is deep apricot if soil pH is alkaline. I constantly have to top it with biochar at pH 8.6 to prevent blooms from turning pink. Carding Mill is much smaller than Crown Princess Mag, but gives way more blooms. Carding Mill is a constant bloomer, but CPM is long pause between flushes. Some pics. of Carding Mill, 11th-year own-root in my zone 5a garden in alkaline & rock hard clay. Carding Mill is very small & compact at 2.5' x 2' as 11th-year own root: Carding Mill has the nice apricot color plus zillion of petals for the vase:

I have Carding Mill own-root now and after two years it's a foot high and might have had one bud that I took off. I had it before on root stock, I think from Austin, and it exploded and bloomed all the time and did not frizzle as I remember Monsieur Tillier and Clementina Carbonieri did that I planted nearby. It's hotter and drier now but I think this is still a good rose for a hot inland climate, especially if you can give it late afternoon shade. I hope that my dwarf will grow and give me a bloom or two before I die but I'm not counting on it. My only hope is that this rainy winter might have given it more of an incentive to thrive, although it had plenty of water before then. I don't grow the other rose, and in fact don't have any of the newer Austins. If I were you I would give Carding Mill a try, only not own-root, unless I just ended up with a dud. Edited: I cross-posted with you pat, but your rose is gorgeous. Sorry about the blackspot. My former one never had any disease and neither does my present dwarflet.

I bought my Francis Meilland from a nursery clearance three years ago as a half-dying potted bareroot rose, and it bounced back pretty well. I put it in a pot for one year, and after two years being in the ground, no matter how hard I pruned it back, it grew to 7 feet tall. (I removed about 3 feet from each stem after the first flush.) It's not stingy for me at all, blooming regularly every 5-6 weeks. Maybe it just needs some time to mature. I only fertilized once in March and water my roses every three days in summer. We're not as hot as other states/countries, though. Photo taken 3 days ago.
