I wanted to wait to review this artificial ivy until I actually had it hanging and exposed to the elements for quite some time.  Ours has been outside and subjected to high and low temps of 35 degrees to 105 degrees for over two years now.  And I can honestly say it has maintained its color and foliage extremely well.  I have to say, I am pleasantly surprised and want to buy more.  I love the green it adds to my patio/pool area.
