Yes, thank you. That's why I don't have many vines, no good places to put them in this yard. (Saw sweet A Clem eat a 6-foot privacy fence before, no thanks, you're right!) And you're right, trying to propagate by dropping a piece can be so much harder than trying to eradicate by making sure you don't! But after seeing Mom's getting devastated every year, and several failed propagation attempts, I didn't think it would have the energy to make wayward runners, didn't see that from watching hers all of those years. It's a good defense mechanism for a plant that gets eaten though. An admirable trait. I put this in a kind of wild corner with Lantana and Buddleia anyway. A few smaller plants can easily be relocated if necessary. The big wild things can duke it out, there's mowed lawn around the bed, the carport shed. Obviously this is already past the point of being able to be dug up but I don't want to, I want it there. The whole bed exists for the benefit of butterflies in general. Guess I'll find out how far away the shoots can go... If it can take quite a bit of shade, I could put some along the back fence too, where anything but PI or Kudzu is permitted.
