Vertical Gardens – An Innovative Element of Green Building Technology: A vertical garden also known as green wall or living wall is self sufficient vertical garden attached to exterior or interior walls of a building. They differ from green facades (ivy walls) as green walls have growing media supported on the face of the wall, while green facades have soil only at the base of the wall and support climbing plants on the face of the wall to create the green, or vegetated, facade. The plants receive water and nutrients from within the vertical support instead of from the ground. Vertical garden was invented by Stanley Hart White who patented a green wall system in the late 1930s. In vertical gardens, various types of modular panels can be used along with geo-textile fabrics, growing media, irrigation systems, and plants. Living walls are particularly suitable for cities, as they allow good use of available vertical surface areas. The living wall could also function for urban agriculture, urban gardening, or for its beauty as art. Green walls may be indoors or outside, freestanding or attached to an existing wall, and come in a great variety of sizes. For more details please refer below link
