The pioneer in vertical gardens or 'le mur vegetal" is a French botanist and artist Patrick Blanc. He got his inspiration from traveling throughout Asia, where he observed lush vegetation growing in remarcable places and at any angle possible. Patrick Blanc has worked on various projects, external and internal vertical gardens thoughout France, Japan, Taiwan, etc. Patrick Blanc has installed around 250 vertical gardens worldwide and visits each garden every 2-3 years to obtain the right insight into the development of plants and general state of his vertical garden. He also often receives images from garden carers as a feed-back.
One example of the vertical garden is located in a modern, business area of Paris, La Défense. In addition to glass and concrete skyscrapers that may give of image of cold and lifeless place, there are large number of green spaces created that enrich this space.
One example of an integrated vegetation is a vertical garden on the entire front wall of the back entranceof 'Qu4tre Le Temps' shopping center. These plants are not planted in earth, but in geotextile that is watered with mineralized water, which is poured back and re-used after going through the whole system of a vertical garden.
In addition to vertical garden, indoor garden is integrated and is a perfect spot to relax after some tiring shopping. The shopping center Qu4tre Temps is usually crowded, however the difference in freshness and quality of indoor air is more then evident if you are close to indoor garden. Integrated garden has a very high aesthetic value, but also serves as a natural filter, absorbing CO2, small particles and pollution.
