Quote: Kass, we have the wild passion vine on our place too. They always come back in the same place where they were the year before. This may be from the older vines or they could be reseeding where they are established. Some of our vines are really big...so they might be coming back on the old vines. Some are large enough to give a "roof" on a few big brush piles we left for the wildlife in the back pasture. I wouldn't cut them back and I would use leaf litter to mulch the roots. My Aunt had one at a house she rented years ago. It was growing on the chain link fence and was there for several years. Maybe it's like a Clematis.vine.
