Greenbrier has to be the most wicked of vines. With sharp stinging briers and tendrils that will wrap around other plants and choke them to death. It even wraps around its own stem as you can see, but it won't choke itself. Wicked vine! More info here - http://namethatplant.net/plantdetail.shtml?plant=1402
@dutchothotmailcom Thanks, Esther! I wanted a sharper focus on those tendrils. It's a little hard for me to shoot. LOL! I'm not as limber as I used to be.
