Vertical gardens of Patrick Blanc

Look at the beautiful vertical garden architecture of Patrick Blanc.

Plants don’t need soil in any situation because the soil is merely nothing more than a mechanic support. Only water and the many minerals dissolved in it are essential to plants, together with light and carbon dioxide to conduct photosynthesis. Wherever water is available all year long as in tropical forests or in temperate mountain forests, plants can grow on rocks, tree trunks, and slopes free-of-ground.
