"With this garden we are trying to show how a roof garden can be just that - a garden. The traditional approach to roof gardening is either to have a few containers with plants, or to re-create a traditional garden that can put a great strain on a roof. Our garden uses a thin layer of light, free-draining soil, and plants that are specialy selected to grow in dry conditions on hot, exposed sites."
