Vertical Gardens Patrick Blanc

Nobody is more familiar than Blanc with the secrets of the plants, from all over the world, that live on almost nothing, in the most unlikely situations, carpeting the forest understory in semi-darkness or clinging to rocky cliff faces. From Paris to Bangkok, from New York to Singapore, Blanc invites nature to flourish on the walls of museums, shopping malls, private homes, big hotels, and skyscrapers. His works have brought a breath of fresh air to urban environments, changing our view of the cityscape, orchestrating and bringing art into the heart of the city, transforming concrete walls into refuges for biodiversity.
