Annette, that Clemmie looks great with the Japanese maple. Nice photo of the passion vine too.
I wish I could get pink jasmine to live here, it is borderline but I've had it die several winters so I give up. I'd put one in the greenhouse but it is too small, it would swamp it. My star jasmine barely blooms though has lived at least. Both of them have amazing fragrance.
Clematis respond extremely well to severe pruning.
None of mine are close to blooming yet, it has been very wet, gray and cold here this spring.....
