How often do we overlook bark, a frequently beautiful and always important part of the plant, focusing instead on leaves, flowers, and the shape of the trunk and branches? Hugues Vaucher, a Swiss watchmaker with a lifelong fondness for trees and an eye for detail, illustrates the rich variety of colors, patterns, and textures of bark with more than 550 photographs in "Tree Bark: A Color Guide." Originally published in French and German in the early 1990s, this new Timber Press edition has been improved and expanded to include more than 440 species and varieties of trees from around the world.
