In recent years, "green walls" have grown in popularity among urban space developers.
Local authorities view them as a suitable and eco-friendly replacement for the optical-illusion-style painted walls which cover building façades and which (unfortunately) can be seen on street corners everywhere as relics of the 1980s. If you want to know more about this phenomenon, simply follow the guide.
Technical aspects :
Vertical gardens or ecosystems are designed to be attractive decorative items, as well as a piece of urban ecology in their own right. The possibilities are endless – from rockeries to bioengineering. You could simply insert plants suited to nutrient-poor, dry environments, or use more sophisticated techniques to improve the plant colonisation and growth conditions using substrates that can absorb and release water (peat, coir, etc.). Alternatively, you could use grow the plants on synthetic horticultural felt to provide them with sufficient nutrient-salt-rich water. In this situation, the plants are watered via a closed circuit, which is adapted to the specific climate. But green walls don't just look pretty! They can also act as a shelter or source of food for birds and invertebrates, as well as creating their own microclimate and improving air quality.
In the world of famous botanist Patrick Blanc, green walls become true works of art...
Patrick Blanc is a colourful character who specialises in creating biodiversity in urban spaces and transforming bland concrete landscapes into blooming works of green art. He is an expert in rare plant species, successfully incorporating them into vertical art forms, where soil and water are scarce and shade is never far away. He has created green masterpieces in cities from Paris and Bangkok to New York and Singapore, transforming the walls of museums, shopping centres, homes, hotels and skyscrapers. Some of his best projects are included in his latest book, "Le mur végétal" (The Green Wall) (Michel Lafon – 2011).
