Vertical Gardening is a new concept in the gardening world. Vertical Gardens are also referred to as living walls, bio walls, or green walls. Patrick Blanc is the inventor of the modern Green Wall. His ‘mur vegetal’ projects being the best known of modern Vertical gardens or Green Walls. A Vertical Garden can basically grow anywhere, in homes, offices, schools, galleries, museums, hotels, shopping centers, airports, restaurants, cafes, bars. The list is endless. Basically, anywhere there is a wall or a flat horizontal surface.
Plants are attached to the exterior or interior of a building or surface. Plants root in a structural support which is fastened to the wall itself. The plants receive water and nutrients from within the vertical support instead of from the ground. Vertical Gardens can be a solution for screening walls, introducing greenery in urban lifestyles, promoting interest in gardening, improving air quality, lowering energy intake and introducing an interest in horticultural art. Almost any kind of plant can be incorporated into a vertical garden, including annual, succulent, perennial, ground cover or vine plants. These container gardens can be used in locations where there is not much space, such as patios, balconies and small courtyard gardens.

• A Green Wall acts as a bio filter, enhancing air quality by breaking down harmful airborne contaminants and transforming them into clean oxygen. Like a green roof, a green wall absorbs carbon dioxide and releases oxygen and therefore reduces green house gases in the atmosphere.
•In urban surroundings, vertical gardens may be an ideal way to introduce a natural element to the lives of city-dwellers.
• It retains rain water that would otherwise run off the side of the building and overflow sewer systems
• Green Walls reduce energy consumption by providing a layer of insulation around the building. This keeps the building cooler in summer, reducing the reliance of air conditioning. As well as protecting the building from the cold in winter. This layer of insulation also protects the building’s facade from harmful UV rays and other damaging weather conditions, as well as creating a sound barrier.
• Living walls can help cut your food bills. A number of edible plants can be grown on living walls, including many herbs, salad greens, and other vegetables and fruits.
