Vertical gardens or Green walls create green spaces seemingly out of nowhere. 10 sq ft of space can give you 100 sq ft of green space. They create greenery or a splash of colour and can be artistic or abstract with the inclusion of other materials such as wood, metal, flowing water or other elements. Indoors they help in purifying the air and decrease the temperature in closed spaces.  In offices they are a soothing influence and create better working spaces. Plants reduce stress levels to facilitate better productivity. Green walls are now used in bathrooms, as outdoor screens and in city streets to cover up concrete constructions.
