Beautifully illustrated with over 130 color photographs, this new, revised edition of the classic text on hydrangeas shows the enormous possibilities offered by the plants, describing 20 new cultivars not in the original edition. The first section provides information on natural history, cultivation, and propagation; the second section describes 100 cultivars, including salient characteristics and even leaf and sepal outlines. The information is highly readable, yet full enough to be used as a guide to identification. It's easy to see why the book is a classic, and no hydrangea enthusiast will want to be without this new, expanded edition.
Hydrangeas: A Gardener's Guide by Toni Lawson Hall (Timber Press 2005)(635.933372). This volume is made for the hydrangea enthusiast. The first half of the book deals with hydrangea cultivation; the second half is a catalog of cultivars. The information contained herein is easy enough to intrigue novice plantsmen but specific enough to satisfy the experienced hydrangeaphile. My rating: 7/10, finished 2007.
