This book is divided into four Part I consists of winter and summer portraits of deciduous trees photographed from identical positions and juxtaposed to dramatize seasonal transformation and portraits of evergreen trees. Part II contains the text, which covers such matters of concern to the architect and layman as the protection and preservation of trees already existing on the building site, problems involved in planting trees in cities and on rooftops, cost considerations, lists of trees for special uses, and Mr. Zion's personal approach to designing with trees. Part III consists of design data that give outline descriptions of each tree pictured in the portrait section, including such basic information as height, spread, texture, blossom, fall color, rate of growth, and zone of hardiness, as well as suggested design potential. Part IV provides lists of trees for use in each of the United States except Alaska and Hawaii.
A great introduction & summary of trees within the context of landscape architecture, or architecture in general. Also would serve well as a reference, which is more likely its intended purpose. Doesn't by any means list every tree, or even all the ones you might want to use, but it covers a vast quantity of them nonetheless. There are lots of useful details on each of them, from appearance to logistics, as well as design advice for how certain trees are best used.
