Pretty pics, J. I initially had a fall clematis in my lilac, but it was a bit too overwhelming. It was gorgeous in bloom, but we ended up having a heavy wet snow in the winter which was caught in the clematis twinings and snapped a lot of limbs. Out it came the following spring. Yours appears to be in a sizeable tree that can handle it.
How does the hummingbird vine climb? That looks like a good candidate for my plum tree, it would be really pretty if it bloomed against the purple plums. I'll have to check into that one.
