Can I grow passionflower in WA?
I just saw an article on this vine in one of my garden magazines, and the beautiful flowers took my breath away. I'm wondering if it is hardy in my climate, I'm actually zone 7 in WA state. It would have to go in a container, and I want it to wrap around my deck railing. The summer temps are now regularly in the 70's-80's, but winters can get down to the 20's. Is there any species of passionflower that will work for me? thank you!
