So, as mentioned before, I have some passiflora taking over my front garden. It's very unusual and beautiful, but extremely invasive. I had never seen it before and I've been wondering why my garden suddenly started growing it. Do you think it could have been from the mulch I put down this summer? I don't remember any of these vines before I put the mulch down. Is it possible it could have been brought in with the mulch? None of my neighbors have these vines so I'm thinking it's not native to my little area.
