This book is written to demystify hydrangeas. It discusses the science, and how to grow them to provide what the marketing hype promises. It covers all aspects: pruning, fertilizing, irrigation, light exposure, soil composition, etc. It is NOT a rundown of all the options in the marketplace: that is a moving target with continual new introductions. Over 150 photographs and illustrations as well as a handy index can help a reader easily understand specific elements of growing this plant.
