Okay, that is definately NOT ground ivy..
That leave is wayyyyyy to big..
Now you're sayin' it's a vine...
does it have any climbing tendrils?
or how does it "vine"????
*not being funny, but it's not jumpin' out at me
for what it is, so, we then see if we can find the "family" it's in*
***that is, unless someone does identify it.***
but I need (please) a vine section, or other identifing traits..
*give it a wee~bit of time, others may very well come thru and KNOW IT, I just don't*
But we'll get you close to knowing it..
