There was a horror movie a few years back called ‘The Ruins’, https://en.wikipedia.org/wiki/The_Ruins_(film), where there was a monster vine in a Ancient Mayan pyramid. I think they used the Trumpet Vine for the ‘star’.....................
Yes, I saw that movie but I think the leaves on that vine were different.
The vine is beautiful in April. I’d like to plant it in a couple of other places along another fence. Just need to get some viable cuttings that will grow.
