Vaporvac: I bought Shocking Blue, Zeph. Drouhin, Savannah, and Orchid Romance. Really kick myself for NOT getting those huge bags of MG-garden-soil for roses sold for $4 each at Walmart early spring. Walmart is sold out, same with HomeDepot, and Lowe's selling it for $9 per bag !! My roses which were grown in MG-moisture-control potting soil had wimpy roots and didn't survive my winter, but my roses which were grown in heavy & wet soil like MG-Garden-soil for roses developed THICK & SOLID roots that survive winter and flower lots. It's even wetter than my clay !! For the record: every own-root (be it tiny band-size) or gallon-size which I planted right smack into my dense & alkaline clay survive many winters, but the ones which I babied in pots (with potting soil) grew wimpy roots that didn't survive zone 5a winter, no matter how I did it: be it putting potting soil into the ground, or grow in pots 1st, then transfer to the ground (my alkaline clay) later. MG-garden-soil for roses (pink-bag with pic. of roses) was on sale at Walmart for $4 per huge bag. That soil is AWESOME in moisture-retention. I had 3 bags opened in hot sun over 90 F: Hyponex potting soil, Scott's premium bagged soil, and MG-garden-soil-for roses. Hyponex dried up into hard-granules, Scott's-top-soil dried up to hard-black-pellets, but MG-soil-for roses STAYED WET AND FLUFFY. I moved W.S. 2000 (own-root) right before winter, and planted that in a bag of MG-garden-soil for roses (only $4), plus mixed In gypsum. W.S. 2000 was the 1st rose to bloom (despite being moved), and having 20+ buds right now as own-root. Own-roots have short roots, so they can't reach down below for minerals, best use a HIGH-MINERALS & HIGH-NUTRIENTS soil like MG-garden-soil-for roses, which has black-peat (de-composed humus), plus peatmoss & pH-balanced to neutral with lime. Fluffy potting soil like MG-moisture control can't enable solid roots for winter-survival, like heavy clay or heavy soil like MG-garden-soil for roses. For newly bought own-roots I have to use a HUGE amount of soluble-fertilizer NPK 20-20-20 weekly to get blooms. Potting soil has zero-nutrients peatmoss, plus a few chemical granular-fertilizer. Too much hassle to fertilize frequently so I would rather use a rich & fertile soil like MG-garden-soil for roses, which is dense & heavy & black peat mixed with peatmoss, rather than fluffy-peat-moss-potting soil which produced wimpy alfalfa-sprout roots and thin canes. I have never seen any black soil which retain moisture as long as MG-garden-soil for roses, see below pic. In contrast, there's the lousy rating for MG-garden soil with mostly wood-chips. Below soil has perfect rating everywhere: Walmart-site, and 33 perfect reviews at HomeDepot site:

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). Own-roots with 2 feet of green canes: La Reine (many winters), Blue Mist (since 2012), Prairie Harvest (since 2014), Mary Magdalene (since 2011), Evelyn (since 2012), Radio Times (since 2011), Pat Austin (since 2011), Christopher Marlowe (since 2011), Golden Celebration (since 2011), Lilian Austin (gave away but very hardy), the Squire, the Dark Lady, Wise Portia survived 4 winters but died in poor drainage clay, Dee-lish (since 2015), Twilight Zone (since 2016), William Shakespeare. 2000 (since 2011), Comte de Chambord (since 2012), Princess Anne, Sweet Mademoiselles, Aloha climber, Orchid Romance, Bohemian Rhapsody, Marie Pavie, Lagerfeld (since 2017), Frederic Mistral survived 2 winters but died when I didn't winter-protect with leaves, Sonia Rykiel (survived 3 winters) but died in freezing rain winter, same with 1/4 of the street-trees in my neighborhood, Excellenz von Shubert (since 2013), Own-roots with less than 1 foot of green canes: Gina's rose, Tchaikosky (since 2015), Cornelia (since 2018), Bolero (few winters), Peter Mayle, Sharifa Asma, Neil Diamond, Amber Queen, A Shopshire Lad, Strike it Rich, Old Port (since 2012), Veteran's Honor (many winters), Double Delight (grafted on Dr.Huey), Savannah, Tess of d'Uberville, Gene Boerner (since 2014), thornless Yves Seedling (since 2013), Stephen big Purple (since 2012), Louise Este, Mirandy, Crimson Glory, Liv Tyler survived 1 winter but needs winter-protection, Rouge Royal (bought last year with no winter-protection). 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.

Sarena: if you have a LARGE garden with plenty of land, then grafted St. Cecilia would be good. But I have a small garden, and Lavender Crush (grafted-on-Dr.Huey) steals water and nutrients from the small own-roots next to it. I have rock hard dense black clay, so St. Cecilia is pale as own-root (got choked by my dense clay). But you have fluffier & more nutrients red clay, so St. Cecilia might not be pale. My clay is rock hard so grafted is less likely to sucker, but I took me 1.5 hours to kill a Knock-out grafted on Dr.Huey. I found its roots extending 4 feet away to steal water from my annual flowers. It's impossible to plant any pretty flowers around roses grafted-on Dr.Huey. But I can plant pretty flowers next to my own-roots without worrying about water being stolen or invaded by Dr.Huey or Fort-rootstock. Below are Christopher Marlowe and Pat Austin, both are 11th-year own-roots:

I really like the Morden blush. It is the most productive rose of my small garden as it never stop blooming from june to september. It is not a very tall plant, I guess it won't surpass 4 feet and it does have rather ugly 'feet'. Nonetheless in a mixed border behind white salvia and in front of a taller plant it is really pretty and always in bloom. Health wise, it did have a lot of blackspot at the end of last summer but we had a horribly wet summer (the worst I can remember) and I don't spray. Also, my rugosa alba next to it was infested with aphids and mildew (don't worry it comes and go without any real impact, it is a really tough plant) but it never affected the Morden.
