This is a useful paperback "guide to growing Alpines and other wildflowers in the American garden". Over 2/3rds of this book is devoted to a wide variety of plants that can be grown under these conditions. No color photos, only drawings but the descriptions and information is useful and the descriptive catalogue of plants will enhance your interest.
