Dirr's encyclopedia of trees and shrubs

"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.
