many garden-worthy natives. The main emphasis is on woody plants. Almost all Pacific Northwest native trees are reviewed in some depth, includ- ing those not recommended for a garden setting. In the chapter on deciduous shrubs, 10 “choice” species are first considered as the best options. Much of the writing in the plant descriptions is the voice of Kruckeberg, although I noticed that favored plants are now “our” favorites—the two authors agreeing on most of the selections. Chalker-Scott has added a new chapter that brings her signature work on horticultural science to the establishment and maintenance of a garden rich in native plants. She alleviates concerns about using “nativars”—propagated selections chosen for an unusual and desirable trait, such as double flowers or variegation. She also assures the new gardener that it is okay to mix well-behaved exotics into your garden of mostly natives. One major difference between the second and third editions is the removal of any instruc- tions on how to collect native plants from the wild. Chalker-Scott cautions, “This practice must stop if we are to retain many of our rare, threatened, and endangered species. It’s a better ethical and ecological choice to purchase native plants from reputable nurseries that have propagated and cultivated their plants without endangering native populations.” Enhance Your Native Plant Gardening Library Since the publication of the first edition of “Gardening with Native Plants of the Pacific Northwest,” other authors have addressed the same topic. If you are considering using natives or establishing a native plant community, I recommended you buy (or check out from the Miller Library) a couple of other titles. “Native Plants in the Coastal Garden” (1996, revised 2002), by April Pettinger and Brenda Costanzo, brings a British Columbia focus to native plant gardening. Essays describe the rise of a late 20th century naturalistic aesthetic in European and American garden design and the supreme suitability of native plants for this look. Many different design aspects are considered, such as container gardening with native plants, and the large role that grasses play in any landscape. Only in the latter half of the book are species described in depth, presented in groupings by appropriate habitats. Trees, shrubs and herba- ceous plants get equal attention, and each plant type is given its own section on propagation and cultivation. A couple of downsides: Photos are limited, and most of the information on nurser- ies and public gardens is out of date. I reviewed “Encyclopedia of Northwest Native Plants for Gardens and Landscapes” in the Fall 2008 issue of “The Bulletin.” The three authors are from southwestern Washington and take an encyclopedic approach to their topic: The introduction and appendices are brief, but the core is very substan- tial. Propagation, cultivation and ethnobotany are included in the species descriptions, and both color photographs and line drawings make this book good for identification, too. At the time, I wrote, “This book is a must-have!” Now, I think the serious native plant gardener should have all three of these books in the home library. Both of the older books proclaim the same admonishment as Chalker-Scott against collecting in the wild, but offer propagation help if you wish to increase plants already in your garden or in that of a friend.
