Report an issue with this species

The English elm is a historic ornamental deciduous tree, notable for its rapid growth, large crown, and deeply fissured bark. Despite its name, it is a clone believed to have been introduced to England by the Romans. It suffered catastrophic losses from Dutch elm disease.
