I own several books on ornamental grasses. This is one of the best books for illustrating how to work ornamental grasses into your landscape. It is short on text but long on really great photographs of grasses in the garden.
Many books have excellent close-ups of individual grasses.
This is the book to buy for ideas on how grasses will look with your other plants. Gardening with Grasses, by Michael King and Piet Oudolf. This book is highly recommended. It is a great introduction to growing ornamental grasses. It has a great selection of photographs and very useful text.
