The field is wide open. Here is just one (for BS resistance, Aussie Open January heat, and the colour range you specify): Thank You Rose. Part of kordesus‘ “Sunbelt” collection for performance in heat.

mustbnuts - I think those are beautiful! Beauty is in the eye of the beholder, as they say. You reminded me that when I have friends smell this rose, some say that it doesn't have a lot of fragrance, which I find surprising because I can smell it from where I am standing while they are sniffing it with their nose buried in the bloom. So different people might experience it differently. Some of my first blooms 4 years ago: In the heat today (close to 100). May 29 this year: May 9th this year they were little pink cabbages that didn't open up more than this. This is typical for the first flush for me. So as dianela says, the form varies a lot. Even the color varies quite a bit.

Don't know why I didn't think of this one sooner, but what about Aunt Margy's rose? Mine is not even a year old yet but has quite a few of the qualities you're looking for. No pictures, but check out Ingrid's photos from some of her past posts. That's what made me think about trying it. I have no idea how well it will do as a cut flower since I rarely cut mine and bring them inside.

BTW, for those of you who asked, these are Voyage 2 Champagne lisianthus. As for any tips, start them as early as you can. January 2nd worked for me, but I've heard of folks starting them in Nov/Dec as well. Also, I watered them daily with a very low dosage of hydrogen peroxide - 2 cups of water w/1 teaspoon of hydrogen peroxide (3%). Spray twice daily. This made a huge difference in their germination and size. I purchased the seeds from Johnny's Select Seeds and grew the seeds under grow lights from Gardener's Supply. Give it a try. Good luck!
