Hardy Plant Society, Mid-Atlantic Group
The Hardy Plant Society was started about 50 years as a conservation effort for hardy herbaceous plants in England. In the United States, the Hardy Plant Society, Mid-Atlantic Group, is an independent offshoot based in southeastern Pennsylvania. The Mid-Atlantic Group Web site includes photos, group history, programs, archived articles, and events.
The Pruning Book
For pruning guidance, I rely on my dog-eared, 1997 softcover edition of The Pruning Book, by Lee Reich. Fortunately Taunton has reissued this practical and sturdy "how-to." (The revised edition will be available in January, 2010.) Reich's direct, clear writing style and the book's photos and clean line drawings make this an excellent intro for the novice and a smart reference for those of us in training.
