Sounds so lovely and in exchange for our help we demand pictures !! ;)
I had Jude the obscure, it was very pretty but had the weirdest , unloveable scent. Someone compared it to baby diapers before , and that is a close guess. It smells strange ! Of course everyone Smells things different , you may love it ! :)
I had Sdlm and it is just my favorite ! So pretty and fragrant.
Do you like singles ? Darlows enigma is a beautiful fragrant as can be rose!
Good luck , sounds like you'll have a dream garden

It sounds beautiful. We once arrived in L.V. just in time to see the Dr. Huey's in some older neighborhoods at their height. I have to say, they were spectacular . . . But also an object lesson about what happens there with the Good Doctor. :-)

Yes, indeed, pictures WILL be welcomed, over and over, as your garden begins to grow up.

I wonder how European once-bloomers do in the Las Vegas climate, and for that reason would be wary of 'Kazanlik'. But perhaps other gardeners in your area can help there. R. moschata plena would be the best for scent of those on your list, I suspect. I seem to remember hearing that old blooms stay on the plant. I have the single and it is fragrant.
Congratulations on your new garden!

Lorri, you have an impressive array of roses. I'm in the process of planting a new rose garden this year as well, and share your excitement. I'm growing several of the roses on your list, but don't have much experience with them yet. I can tell you that Tradescant is an incredible color, true to the pictures so far, even in my 90F - 102F temps.

The one rose I have plenty of experience with is Hot Cocoa. I've had it for years, and have not been impressed. Since the form is just blah to my eye, I purchased six of them based on color alone, and the color rarely presents as it should. I recently pulled and relegated them to a shady area in the dreaded "waiting room", and the color is much truer there, though still not the chocolaty hue it should be. If you ever want a beautiful rose with brown undertones, I suggest Chocolate Sundae. Rich oxblood to burgundy coloration; lovely cupped form. But not fragrant, and not a prolific bloomer for me. Anyway, to capture the intended color, you might want to try your Hot Cocoa in part shade.

For fragrance I love Alnwick and Wollerton Old Hall. Alnwick epitomizes the word "pretty" -- it's like a powder pink ballerina's tutu. And the scent is a delicious raspberry. Wollerton is elegant and deeply cupped. Both have been blooming nonstop. I hesitate to recommend Alnwick for your climate, except that it's doing well in my hot and dry SO FAR. I have one in full sun, and another in part shade, and guess which is doing best? Both! (at least for now) -- let's see how it goes this summer when there is no relief between the hot spells.

Evelyn is another one that's gotten tons of raves for beauty and fragrance in a hot, dry climate, and mine is blooming and looking very promising at this early stage.

Best of luck! I hope your new roses surprise and thrill you the way mine have! I got great advice on this forum, and I'm sure you will too. Below is Tradescant.

I think your alba semiplena will benefit from a northern exposure, maybe north side of the house where other roses might not grow so well. It will only bloom for about 2-3 weeks, but those weeks will be spectacular. You can grow vines, even morning glory, on the alba during the summer with no damage to the plant--well, I wouldn't try honeysuckle, but I found in CA that morning glories were quite nice draped on my albas. Albas can be very effective as part of a hedge of other speices.

Be aware that the toughest part of the yard will be the west exposure, where the combination of hot afternoon sun and drying wind can kill prized plants. If you want climbers do consider the lovely noisettes. "Pleasant Hill Cemetary" and "Manchester Guardian Angel" are two that can take a harsh western exposure.

Also, do make yourself aware of any water restrictions your town may impose. Mulching might save your rose's lives, also a lot can be done with winter irrigation, when the water restrictions are relaxed, to induce your roses to grow deep and strong roots.
