Creating Formal Gardens

I have searched for several years for book(s) that provide advice on how to create a formal garden. Astonishingly, I found none that offer much practical advice beyond pretty pictures and the usual design principles found in most design books. That is to say, I found none until I happened upon this book. It made me feel good to have the author explain that when he began his own formal garden, in the mid 70's he found no practical books either! The volume is full of illustrations showing different examples of key formal design elements, It offers good advice on how to create shaped hedges and screen, topiary, and how long it takes for them to shape up. Small things like how to cut a hedge perfectly straight or flat is also explained. Lists of appropriate plants are included. Highly recommended. This book should be in print.
