Have you found a vine, JackStraw?
I would recommend the native Clematis virginiana, nicknamed Prairie Smoke on a Rope. (My number one reason for getting this... I got a kick out of the name. ) It's a perennial.
The flowers are not very showy, but it was the seed heads that I like. Scroll to the bottom of this link to see the seed heads in winter.

Get two or three plants because this is a plant that is only one gender and you need both for it to go to seed. I have eight of these, some to climb up the house and others along a fence.
Definitely not edible, but then deer and rabbits avoid it, unlike the non-native Clematis that rabbits will eat to the ground when you are trying to establish them. My experience when I used to grow ornamentals. :)
I just planted mine this spring. Some of the vines grew about 15 or more feet. I am working at training some of them to go where I want. I only got one flower this year, but that is to be expected while it establishes.
There is a lookalike C. terniflora that has become invasive in some areas.
