The Visual Method for the Practical Identification and Recognition of Shrubs (and vines and ground covers) -- and an important supplement to existing botanical methods.

The book is in two parts: Pictorial Keys and Master Pages. The Keys are designed for easy visual comparison of details which look alike, narrowing the identification of a shrub to one of a small group -- the family or genus.

Then, in the Master Pages, the species of the shrub is determined, with similar details placed together to highlight differences within the family group, thus eliminating all other possibilities. The details of laurel blossoms on this plate are an example and are followed in the book by details of laurel fruit, leaves, and bark.

All of the 3,550 photographs were made specifically for use in this book and were taken either in the field or of fresh material carefully selected from the more than 20,000 specimens collected. Wherever possible, details such as leaves, fruit, twigs, etc., appear in actual size; otherwise, similar details are reproduced in the same scale.

With their abundance of flower, handsome foliage, robust constitution, and frequently stunning fruits, viburnums are among the most beautiful and versatile hardy shrubs available to gardeners. Yet despite these outstanding qualities, there has never been an entire volume devoted to them—until now. In this definitive, comprehensive, generously illustarted guide, internationally renowned woody plant expert Michael Dirr provides a wealth of information about every species and cultivar worthy of horticultural consideration. Never one to pull punches, Dirr bestows praise on viburnums that deserve it and is frank in his evaluation of other plants' occasional shortcomings. These finely judged appraisals make it easy for the gardener or designer to choose the right plant for the right situation.

Whether you're a home gardener in search of a four-season shrub; a nursery professional seeking woody plants with proven appeal; or a designer looking for specimens that are both functional and guaranteed to impress clients, Viburnums will acquaint you with a group of plants capable of meeting all these requirements.

Michael Dirr has said that a garden without viburnums is like a life without the pleasures of music and art. After reading just a few pages of this unparalleled work, you're sure to agree.

Professor Dirr explains in understandable terminology the basic botanical categories of hydrangeas and how they've yielded the colorful hybrids that are treasured today. He enumerates the horticultural assets and liabilities of each type of hydrangea, and offers invaluable advice on which choices are best for which regions of North America --- the optimum choice for Seattle's misty climate might melt like butter in the steamy heat of Atlanta. Professor Dirr even provides a futuristic glimpse of the interesting and unusual species and hybrids --- including reblooming types --- that will be making their way into nurseries in the years ahead. With treatises on propagation, pruning, breeding, drying, design, and pests and diseases, this book will become the classic reference for gardeners in the United States and Canada.
