Hydrangeas for American gardens

Edición de la obra Hydrangeas for American Gardens

"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."--Jacket.
