Chile's Patagonia region is inhospitable to many types of trees, but those that manage to survive here are known for their majestic beauty. One of them is the coigüe, a gray-barked evergreen that grows to 12 meters (40 feet), with radial branches that resemble a series of stacked horizontal planes. The slow-growing cahuén, or larch, can live as long as 4,000 years. The winter's bark (canelo) tree yields a wood used to make furniture and musical instruments. The fruit of the more familiar carob tree, of course, is a popular chocolate substitute.
