Nik I immediately thought of Ben’s photo tour of a rose garden here in Stockton, CA. Lots and lots of great photos of 6x6 rose bushes in a climate similar yours (that aren’t usually so large in other climates). His photo tour was from the autumn, not even spring, so it gives a great visual of rebloom too. Mostly modern, but so very impressive, especially for autumn. Enjoy. https://www.gardenweb.com/discussions/4943585/pictures-amazing-rosebushes-at-csu-stockton?n=39

Cori Ann, those roses are amazing. What are they feeding the roses? I never knew HT' s can grow so tall. Absolutely, beautiful.

Wow, that is a white beauty. Excellent.

The first thing that came to mind was the DA Shrub, Lady of Shalott.

If I had your climate, one of the first roses I would want, would be Daisy's 'Colombian climber',..which I would try as a large shrub.... It may be possible...perhaps you already have it..

Perhaps you already have it, but I just saw my first real life ‘Mutabilis’ yesterday at Cliffs Low Desert Garden. There are pictures in that post. He had it maintained at about that size, and he’s certainly in a hot and dry climate. That ‘Mutabilis’ was a sight to behold! I had no idea it was such a beautiful rose! It was elegant, variable, unusual, and beautiful all at the same time. Lisa

I believe Nik may already have Mutabilis, but what it really wants to do is grow to at least 10 x 10 feet. The bigger it gets the more flowers it has and the spring bloom is something to see. This is not in the spring but I'm showing this to you Lisa as a warning, since you seem (rightly) enamored of this rose. I no longer have it because it was much too large for a front garden and developed dead undergrowth like you wouldn't believe. It became impossible to maintain over time.

I wonder if it would be best to look at the selections of the Roseraie du Desert listing your size criteria, especially since we don't know what you already have. One of the few I have in that size range is SdlM, and it and its sports should do well in your climate. Mme. Cornelissen is really beautiful.

If Roseraie du Desert's offerings are of interest in Europe, it may be wise to shop them sooner rather than later. The Hooks are looking to sell the nursery to "retire" to California where their children live. Much of their collection is already here in quarantine (perhaps even out of it by now) at one of their children's garden, in preparation for them to potentially open here in the US when the time comes. The nursery has been up for sale for some time, so who knows how soon this may occur? But, forewarned is forearmed. If you want roses from them, I would shop now. Hopefully, when they find someone willing to buy the place, they will want to continue the nursery. There isn't any guaranty of that, though.

For the record 6 ft. isn't a large shrub, roses or otherwise. That said 'Nevada' has more of the specimen style visual character than most hybrid roses. If you have room anywhere for a shrub eventually double your stated size limitation.

I would consider 6 foot a large shrub. If I was 7 foot tall, then maybe not...

No one can put an official footage on such a thing... it's in the eyes and abilities of the beholder..

Nik, I wonder if you can get "Smith's Parish" over yonder? It's a willing grower, though it doesn't mind pruning if it gets overzealous. Mine doesn't have the red stripes or red flowers (I wonder if it needs alkaline conditions for the red stripes/flowers?), but I think it's an extremely handsome plant even without the striping.

Looking forward to seeing whatever you choose,

"Snowbird" is my favorite roughly 6' x 6' shrub (which I consider medium-sized). Probably among the most floriferous of the hybrid teas here -- flushes at approximately 1-month intervals, flowers and foliage always very good. This one on its own roots. Makes great cut flowers, good scent.

Oh, woe, Nik -- according to HMF, 'Snowbird' not so available in Europe -- I should have checked! Other ones in that size range I really like and that are pretty much bomb-proof and floriferous here are 'Lady Ann Kidwell' and 'Golden Wings', which do have European sources. ETA that I just cut a flush off 'Lady Ann Kidwell' to shape her during winter pruning -- she really does bloom all the time.

Oh Catspaw, your ‘Snowbird’ is gorgeous! Just look what you have to look forward to, Ingrid! And don’t worry, I have fallen in love with ‘Mutabilis’, but I know it’s too large for the space I’ve got left:( Lisa

Madame Joseph Schwartz ?? Mine is not mature yet, but I love it! After three years it is about 5'. Maybe someone growing this rose in a climate more similar to yours will chime in...unless you are growing it already... etc.

I have been happy with Snowbird too. The fragrance is lovely. My purchase of this rose was inspired by Catspa's images and report. It is supposed to create a smaller shrub, which is likely inaccurate.

Wow, that Snowbird is gorgeous! And it is listed as one of the roses that Roseraie du Desert offers...

I think Roseraie lists the climbing version, K S, which, ironically, is now not so available on this side of the Atlantic. Vintage used to have it.

Two modern roses which make spectacular free standing shrubs are 'Polka' and 'Golden Celebration'. However the sizes are a bit more like 10' x 10'. I don't know how either would respond to pruning.
