"From majestic evergreens to delicate vines and flowering shrubs, Dirr features thousands of plants with all the essential details for identification, planting, and care, plus full-color photographs showing a tree's habit in winter, distinctive bark patterns, fall color, 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 Encyclopedia of Trees and Shrubs is a critical addition to any garden library." -- from publisher's website.
