Blue Glory Vine (Thunbergia battiscombei)
The flower on this one looks like the blue sky vine. Thought it might be when I bought it but it doesn't climb. So last spring, I bought a clock vine and planted it at the base of that tinder pine in hopes it would climb it and continue those flowers up higher. We're still (me and the plant) working on getting up the tree. (Sorry, you can't see the tinder pine in the picture)
