Excellent, but not superior
Note: I don't do affiliate advertising for books. The following is simply my opinion.
I have a new tree book in my library -- Dirr's Hardy Trees and Shrubs: An Illustrated Encyclopedia by Michael A. Dirr. It falls a little short of my high expectations, initially, but I still expect it to be a very useful reference. Perhaps in time, I will cherish it as dearly as do most of its reviewers.
The book has hundreds of beautiful color photos of over 500 hardy species of native and exotic trees and shrubs. In the foreword, the author notes that the plants covered in the book will grow in zones 3 to 6, and most will grow in zones 7 or 8. For most species, a photo that depicts a typical, mature plant is provided, along with photos of any particularly ornamental characteristics of the plant.
Many of the plant descriptions include the names of attractive cultivars that are available through nurseries. Unique growing conditions needed by the species or cultivars are mentioned, as well as some of the negative characteristics such as unattractive winter foliage, susceptibility to disease, etc.
My main criticism of the book is that the type of information provided for one species may not be provided for the next. The author wrote about the characteristics of each plant that he considered most important. Sometimes comparisons of specific characteristics between two or more species are possible from his writing, but often not.
For complete sets of data for native species and for comparisons of species, I'll still be turning to Native Trees, Shrubs, and Vines for Urban and Rural America: A Planting Design Manual for Environmental Designers by Gary Hightshoe. For me, Dirr's beautiful photos and engaging descriptions will be a supplement to, not a substitute for, the vast quantity of tabulated data presented by Hightshoe.
I should add that both of these books focus mainly on plants of the United States east of the Rocky Mountains. If you live in the western U.S., many of your native species will not be found in either of these volumes.
