Planting green roofs and living walls

"Planting on roofs and walls is one of the most innovative and fast-developing fields within horticulture and the built environment. This book explores the very latest roof and wall greening techniques." "Planting Green Roofs and Living Walls describes the historical development of both large-scale commercial and small domestic examples from all over the world. It also provides an introduction to the practical techniques required for constructing green roofs including weight-bearing considerations, materials, substrates, draining layers, modular systems, and plants. A chapter devoted to planting considers plant choice in some depth and outlines key characteristics that make certain plants suitable for the extreme conditions encountered on roofs: drought, high light intensity, and wind."--BOOK JACKET.
