The Garden Tree: An Illustrated Guide to Choosing, ... (ISBN 1841880078)

Good Choice:
This books looks to be an excellent choice for someone having difficulty deciding what sort of trees to plant. It's got what you want - pictures of lots of different trees, advice on tree shapes, sizes, climate soils etc. Also nicely presented.

Wrong country:
This book is written by a British writer for a British audience. It is of limited value in the US. Many of the trees shown are not available here. The language is of course British and the meanings of some of the words used are not readily apparent to an American reader. The book does contain good information (for a Brit).
