What do you think/feel about this one? I look at all of these cool species, and then I get very intrigued, and then I think of the years of work, lol :]

My Rosa glutinosa may bloom this year. The seeds germinated in 2011, and I recall your various comments about some roses not blooming in hot climates, due to dormancy issues. Which really goes into many thoughts. "What can this new species bring?" "How can I accentuate the positives, and get beyond the negatives?" I'll definitely be using it with something that blooms well and resists mildew. These sticky-leaved roses. They can mildew. But then the cool features get lost...

Michael, I don't know that tunquinensis would have anything to offer for you in your climate. If you check additional comments Jeff Stover reported some die back of those I sent him when he lived in OR.

I look at this species as a tropical form of multiflora. It's synstylae and the blossoms and inforescence remind me of other multiflora types. I'm currently working with F2 repeat flowering descendants which remind me of other poly derived multifloras.

Polys are generally well adapted to Southern climates but I'm hoping those derived from tunquinensis might be better adapted to heat and perhaps offer additional resistance to Blackspot.

Some of the tunquinensis seedlings I grew out where susceptible to Powdery Mildew. The specimen I have here is clean, so far.
