Other Details:  The Quercus suber is commonly called the Cork Oak because its bark is the primary source of cork for wine bottle stoppers. The bark can be harvested every 9 to 12 years and does not harm the tree. For 100’s of years the Cork Oak has been planted in Europe due to its hansom and rugged branch structure and as well as its cork harvesting. This is one of the most interesting trees to have in any landscape and is also one of the best oaks for the desert.
