Perhaps it’s time to think about vertical planting or a living wall? We spoke to leading architects and landscape gardeners who shared why the “living wall”—a planting that grows upwards—is a growing gardening trend. I let them guide both the feel and the aesthetic of a living wall, and I’m drawn to planting that’s exuberant and dynamic. Our answer was a living wall, which offers abundant texture. Up this high, weight was a constraint, but the vertical garden is the lightest in London at just 25 kg per square meter.”
