Comments
General Comments: | This tree is subject to Dutch elm disease. While not as much a problem in Florida as further north, it should be a concern for anyone planning to use this species in a landscape setting. In most of eastern North America, this tree has largely disappeared from landscape use due to mass mortality from Dutch elm disease. |
