I am hoping someone can help me out with some suggestions. I am in Zone 7 in SW Oklahoma. I am looking for a vine to put on my chainlink fence that is evergreen and that can take full summer sun. I know about honeysuckle and jasmine, but I was wondering if there are other alternatives. I have come across the Chocolate vine and I thought that might be one choice since it is hardy to -22 F. But it is only evergreen in Zones 8-9 and I am not sure what this will look like in the winter here. I was also looking at Actinidia Chinensis. If you have any suggestions I would really appreciate it.
