A green wall is a wall, either free-standing or part of a building, that is partially or completely covered with vegetation and, in some cases, soil or an inorganic growing medium. The green wall was invented by Stanley Hart White at the University of Illinois Urbana-Champaign in 1931-38. White holds the first known patent for a green wall, or vertical garden, conceptualizing this new garden type as a solution to the problem of modern garden design. There are two main categories of green walls: green façades and living walls. Green façades are made up of climbing plants either growing directly on a wall or, more recently, specially designed supporting structures. The plant shoot system grows up the side of the building while being rooted in the ground. With a living wall the modular panels are often made of stainless steel containers, geotextiles, irrigation systems, a growing medium and vegetation.
Over the last couple of years, living walls have been popping everywhere. Most often they are found in urban environments where the plants reduce overall temperatures of the building. Living walls are particularly suitable for cities, as they allow good use of available vertical surface areas. They are also suitable in arid areas, as the circulating water on a vertical wall is less likely to evaporate than in horizontal gardens. via Wikipedia
