A fundamental resource for realizing the potential of virtually any garden focuses on the resilience and color of stone and includes step-by-step instructions for everything from patios to walls and waterfalls. Original.
I checked this one out of the library, but might pick up an inexpensive used copy to have for future reference. Lots of great photos and ideas for using stone in your landscape - from gravel, to flagstones to rock walls and water features. I was mostly interested in the path and patio ideas, but found a lot of the photos inspiring. I especially liked that there were a lot of examples with drought tolerant plants in the photos, which is what we need in our yard!
