Thank you so much Diane. I can't speak about many of these roses but I had Ambridge Rose years ago and within weeks it was totally covered in rust, the only rose in my garden at that time to have rust. Abraham Darby withers in the sun and now that I have it in the shade also has rust. Carding Mill is excellent for a hot dry climate so that one is certainly correct. Interestingly, when I visited the Austin rose garden at the Barona Casino last August, the only rose that was blooming well from David Austin's list on a blistering hot day was Sophy's Rose. Some blooming well there were Miss Alice, Anne Boleyn, Charles Darwin, Lilian Austin, Mary Magdalene and The Ingenious Mr. Fairchild. It does make me wonder how Mr. Austin acquired his data. Since their American branch is in Texas I would think that would be a good source of information on dry-heat tolerant roses. It would be interesting to hear from anyone who has grown the roses listed by Diane in the heat. Ingrid

I live in Zone 10 southern California, but within the coastal zone which has misty conditions spring-earkt summer, then settles into a true Mediterranean climate by August which continues till December when the rains start. Many roses will mildew, ball and sulk here during spring - early summer, and then after the dry weather takes over in August, the same sulky roses will bloom beautifully and have clean foliage till December. I tried growing Carefree Beauty last year - probably planted it in June - a nice healthy ownroot rose from ARE with really strong roots. After the first few weeks in the ground and a promising initial burst of growth, CB just sulked and mildewed. It did not improve after the dry sunny late summer settled in, so I shovelpruned it in December. I sometimes gift unhappy roses to a friend's garden in Topanga Canyon which tho inland from Malibu has 100+ temps in the summer, and these roses are often very happy there as long as they get enough water. So maybe CB would do better in a more classic southern California climate than my microclimate provides.

Below is the info. that Floweraremusic (zone 5) in Washington gave on her 2020 winter-survival. She has alkaline clay with rocks at bottom like mine & less snow in winter: "My hardiest roses are the Canadians. John Davis, John Cabot, Wm. Baffin, Morden Sunrise, Morden Blush and Morden Centennial, Victorian Memory aka Isabelle Skinner, also a Canadian rose. All these only have tiny bit of tip damage and bloom a lot with no special care. Also, my Hybrid Perpetuals only have tip damage after winter. Magna Charta, Mrs. John Laing, Black Prince and Marchesa Buccella. The only negative is they don’t have long enough cutting stems. All my Austins are very hardy. The one I just can not grow is Jude. Leonardo da Vinci is super hardy and always healthy. Quietness comes through winter very well. Even Rouge Royale survives beautifully. Cinderella Fairy Tale is very hardy. Gruss an Aachen also. Ballerina and Marjorie Fair are both hardy. Poseidon, Princess Charlene de Monaco and Crazy Love didn’t do as well as I’d hoped. The surprise losses this year are Quicksilver, and Dames de Chenonceau who is left with only 1 cane. Versigny is also reduced down to almost nothing. This was a mild winter with very little snow. " Floweraremusic (zone 5). From StrawChicago (zone 5a with hard black-gumbo alkaline clay & less snow but with freezing rain in winter). Versigny didn't survive winter either. So I lost Versigny TWICE. Besides Versigny, other wimpy own-root roses that don't survive winter well: Paul Neyron, Anna's Promise, Pink Peace (own-root died 1st winter, but grafted-Pink Peace survives many winter), Elantyne, Jude the Obscure, Young Lycidas (bought as grafted-on-Dr.Huey, now with only one cane), Mary Daly, and many floribundas don't survive my zone 5a: Pink Chiffon, Sheila's perfume, King Arthur, Deep Purple, Shocking blue, Honey Bouquet (survived 1 winter). Polka Climber (survived 1 winter), Cloutilde Soupert (died twice on me). Sutter's Gold didn't survive winter, same with many fragrant mini-roses from Burlington nursery. Below are my hardy OWN-ROOT roses in my zone 5a alkaline clay, only Double Delight, Young Lycidas and Lavender Crush are grafted-on-Dr.Huey. Bold-faced are the very vigorous ones: Own-roots with 3 feet of green canes: Carding Mill (since 2012), Princess Charlene of Monaco, Duchess de Rohan, Crown Princess Magareta (since 2012), Zepherine Drouhin, Lady of Shalott, James Galway, Lavender Crush, Queen of Sweden (gave away but very hardy), Poseidon (right below the rain-spout, dug down to 2.5 feet), Scepter'd Isle (very big & hardy own-root but gave that away with its lousy scent).

Annie L. McDowell (survived 2 winters but needs a wet-spot since it's almost thornless), Nahema (survived 1 winter then died during freezing-rain winter), same with Eyes-for-you (drought-tolerant and doesn't like freezing wet winter), Souvenir du President Lincoln, Madame Issac Pererie and Madame Earnest Calvat, Firefighter (survived 2 winters) but died since it's next to tree. Bayes Blueberry (survived many winters but I gave away), Charles Darwin (gave away since it fades badly), Arthur Bell (since 2012 & killed it since I don't like the flowers). StrawChicago.

We have grown 2 Quietness roses in our CA USDA zone 9/Sunset zone 14. We usually around 10 to 30 days with temperatures of 100 deg F. or more. If you water with a drip system, the roses will send down deeper roots, which aids in their coping with high temperatures. Mulching them will also help. These roses are in full sun and neither my wife nor I remember seeing burned or crisped petals. I think that the blooms last at least 3 to 5 days on the plant, perhaps longer in cooler temperatures. We think that Quietness is among the very best roses released by Dr. Buck. We don't grow Earth Song, but do grow Distant Drums and Prairie Star, which are also both excellent.
