'Lincoln' is distinguished by retention of its dark-green leaves well into autumn [1].
Although reported (in patent) to be resistant to Dutch elm disease, it has not been widely tested [1]. In trials in Oklahoma, the clone was heavily to severely damaged by the Elm Leaf Beetle Xanthogaleruca luteola [2].
Reputed to be a very cold-hardy [Zone 3] tree. 'Lincoln' is not known to be in cultivation beyond North America.
