Patrick Blanc is a French botanist and lanscaping and gardening expert.
After many years of research and testing around the world, Blanc has created, developed and copyrighted the Vertical Garden, an amazing way to build vertical gardens without any soil.
These vertical gardens are self-sustained. With little maintenance they grow and the owner is car free, because the whole system takes care of itself.
At the same time, these wonderful vegetal wonders are a smart way to have a thermal and sound isolation.
Patrick Blanc chooses careully the vegetal species utilized in each one of his projects, according to the local species, so the whole Vertical Garden has zero environmental impact.
