Have you seen the new artificial ivy to make green walls?  I found artificial ivy at a Global Syn Turf dealer's showroom.  Once you see the application pictures of the artificial ivy on walls and fences you will see the many different uses.  I ended up buying the SuperHedge Hawthorne ivy for my backyard fence and for a wall on the side of my house.  You would not believe how realistic.  I can't believe they make artificial ivy that looks so natural and real.  The artificial on my chain link fence in my backyard gives me so much privacy and now my neighbors can't see into my yard.  I recommend if you haven't seen the artificial ivy yet that you call Global Syn Turf, ask for a local dealer near you and go get a free sample of the ivy and look at the different application pictures on display.  5 Stars...
