The Botanist Patrick Blanc’s is a CNRS researcher , who used to like to observe tropical plants grow in their natural environment. He had the idea to recreate the vertical rainforest. The idea is simple yet still great: Plants are placed on a vertical support on which they have their roots . They are drip fed by a nutrient solution that flows from top to bottom in the vertical support.
The green walls of Patrick Blanc are all without soil, like tree trunks and rocks rain forests. The result is an extraordinary vertical wall of plants- generally tropical. Now they have been colonizing cities hotel, restaurant and shop. They give back to plants their place in the city. Just as a green oasis, the green wall on a big building is like the heart and lungs of the city.
