or 'Living Wall'. Here's two nice ones, used to great effect on two modern buildings. First one at La Défense outside the new entrace to the 4 Temps shopping centre.
The second living wall I saw this weekend was framing the entrance to the Jean Nouvel building for the Fondation Cartier d'art Modern in 14th arr, Boulevard Raspail in Paris.
I liked the use of lights at La Défense and loved the lush, jungle effect of this living wall outside the Cartier Fondation, especially since it has bare branches sticking out of it just waiting to burst into leaf in spring so the wall will change with the seasons. Really effective use of greenery in a fairly stark modern building.
