I grew up in Mississippi, and we called them ‘Cow Itch’. They grew wild along roadsides and up into trees like Kudzu.
We have them in Florida, too, and all across the Southeast.
That’s why I couldn’t understand Danie_2023’s post of wanting to ‘propagate’ them.
Heck, you can’t stop them! Once established, you need a flame thrower, bulldozer and a gallon of Roundup to kill them!................
Speaking of kudzu, last time we drove through N Carolina (early May), there were lots of dead trees with kudzu hanging off them still. They haven’t figured out how to kill that stuff yet, have they?
It must be a different vine then. I wouldn’t mind it propagating like that. I would have lots of potted vines and a lot to give away as ‘freebies’ to friends.
I have lemon balm and mint that is taking over where I planted it. And the lemon balm has spread throughout the entire yard. I just dig up, pluck and prune it wherever I don’t want it to grow.
