|Other examples of vertical gardens|
Musée du Quai Branly is a museum of African, Indian and other arts located in Paris. The entire facade is covered with 15.000 species of plants from China, USA, Central Europe, Japan and is work of a botanist and an artist Patrick Blanc. The plants are mostly composed of mosses and ferns that are more resistant to external conditions and wider changes in temperature, exposure to the sun and atmospheric precipitation. The external vertical walls should be checked 2-3 times a year. Patrick Blanc has installed about 250 vertical gardens all over the world and visits every 2-3 years to have examine and to have an insight into the development of plants, as well as general condition of the wall. He also regularily receives photos of his vertical gardens from people that maintain them in order to inspect the situation and the growth.
