3500 photographs. Over 380 genera. More than 3700 species and cultivars. With Dirr's Hardy Trees and Shrubs and Dirr's Trees and Shrubs for Warm Climates, Michael Dirr set the gold standard for horticultural reference. This season, Timber Press is proud to publish his seminal work, Dirr's Encyclopaedia of Trees and Shrubs, the most comprehensive visual reference on this important subject. From majestic evergreens to delicate vines and flowering shrubs, Dirr features thousands of plants and all the essential details for identification, planting, and care, plus full-colour photographs showing a tree's habit in winter, distinctive bark patterns, fall colour, and more. In a class by itself for its quality of information, the best researched recommendations for hardiness in the industry, beautiful photography, and Dirr's own preeminence as a master plantsman, Dirr's Encyclopaedia of Trees and Shrubs is a critical addition to any garden library.
