I am not having any luck at identifying this weed, can anyone help?

I live in North Carolina-This weed seems to always pop up in my natural
areas.
Right now we are having a warm spell and my garden is overtaken with
it.
roots are fibrous, no leaf hairs,leaf edges are smooth and fairly
small,it crawls along and likes to wrap itself around other plants.

THANKS FOR ANY HELP IN ADVANCE.
