Parisian architect Édouard François is the master of the green façade; unlike living walls, the vegetation is planted in soil and survives without a lot of technology and pumps. His breakout building was the Flower Tower and the Tour Végétale de Nantes, would have been a sort of elliptical version of it, had it not been cancelled. (Thanks, commenter Gwendal)
Wavering elliptical balconies surround the 17 storey structure, providing the static unit with a sense of life and movement. defined by its lush green facade, the building is layered with thin metal tubes that support a collection of plants grown by the local botanical garden. The containers - which measure 12cm in diameter and 4 meters in length - will be dispersed along the terrace railings, and are thought to successfully recreate the natural conditions of the chasmophyte vegetation.
My first thought was to wonder how big a plant can you get at the end of a 13" diameter pipe, but chasmophytes are plants that grow out of rock crevices and don't need a lot of soil. In fact, they are "capable of growing in cracks completely devoid of organic soil." François certainly has a lot of experience with that, as shown in my favourite project of his, the Sprout Building in Montpellier.
