French botanist Patrick Blanc's vertical gardens at Sydney’s One Central Park
One Central Park’s two towers, house 35,000 plant vertical gardens. Central to the 1200sqm vertical garden design is Blanc’s insistence that plants do not need soil to grow provided they have something to attach themselves to. Light, carbon dioxide water and nutrients are mechanically dispersed to the plants and facilitate their growth and survival. This approach eliminates the need for soil, making it possible for plants to grow on buildings without compromising the structural integrity of the building.
