Quai Branly Museum

The office wing of the controversial new Quai Branly Museum, designed by Jean Nouvel in Paris has a "vertical garden" installed by Patrick Blanc. The construction of the vertical gardens include layers of felt, plastic and metal sheeting which provide a barrier against damaging roots. According to Business Week, Le Mur Végétal, or Plant Wall, is a dense sheet of vegetation that can grow against any surface, or even in midair. It works by doing away entirely with dirt, instead growing plants hydroponically in felt pockets attached to a rigid plastic backing.
