Book excerpt: Since the first edition was published in 1992, Nick Robinson's The Planting Design Handbook has been widely used as a definitive text on landscape architecture courses throughout the world. It remains one of the few titles written by a practicing landscape architect and educator who is also a horticulturalist and accomplished plantsman, and which deals with the application of planting design on a large scale in landscape architecture and urban design projects. The Planting Design Handbook is distinctive for its elegant integration of an ecological approach with an understanding of visual and spatial composition. It emphasizes the role of vegetation layers and designed plant communities in complex and diverse plant assemblages for all kinds of sites and uses. This expanded and comprehensively updated third edition still provides a complete examination of principles and practice of design for public, institutional and private landscapes. It takes account of developments in theory and practice, especially in the use of perennials, and reflects a variety of media and approaches current in landscape architecture and design. All chapters have been revised and re-written to ensure updated references and new references have been added. Many new photographs of planting and projects around the world have been included, with examples of current professional drawings to illustrate the design process. It is generously illustrated, including a colour section and the beautifully detailed line drawings of the Chinese architect and painter Jia-Hua Wu.
