Defying the standards of conventional landscaping, living walls take vegetated ground cover to the vertical extreme. For the past 30 years, French botanist and green enthusiast Patrick Blanc has made a quantum leap forward in the art of gardening by designing and building these living walls all over the globe. Blanc’s latest project—One Central Park Tower—is in Sydney, Australia, where nature’s tranquil features join forces with dynamic city life. The project is a collaborative effort between Blanc and Jean Nouvel. When completed, the major mixed-use urban renewal housing plan will boast the world’s tallest vertical garden.
