Book excerpt: AHS Book Award winner Rock gardening —the art of growing alpines and other miniature plants in the company of rocks in order to recreate the look of a rugged mountaintop—has been surging in popularity. Time and space constraints, chronic drought in the American West, and a trend toward architectural plants are just a few of the reasons for the increased interest. Rock Gardening brings this traditional style to a new generation of gardeners. It includes a survey of gorgeous rock gardens from around the world, the techniques and methods specific to creating and maintaining a rock garden, and profiles of the top 50 rock garden plants.
