Here's an article I just read a few minutes ago about this very invasive vine
What's the name of it ?
Where'd it come from ?
Link to a good photo of it ?
Check the thread "invasive alert" from back in April
"HOPING SOMEONE HAS THESE ANSWERS........"
There are many websites - do a Google search for "mile a minute vine". See the link below for a picture and info.

OK so I went back and checked the thread "invasive alert" from back in April and followed the link there and found this... It's name is Persicaria perfoliata and if you click on "mile-a-minute" you will have the answer to all your questions.
Note.. this site also has info and photos of many other invasives.
