'Ohio' is a moderately vase-shaped tree growing to approximately 13 m in height, the crown much the same in diameter but appears much looser and more open than most varieties. [2] The small leaves are grass-green in colour, turning a dull red in autumn. The samarae too are reddish in colour.[1]
The species and its cultivars are highly resistant, but not immune, to Dutch elm disease, and unaffected by the Elm Leaf Beetle Xanthogaleruca luteola [3].
Initially marketed by Princeton Nurseries, Princeton, New Jersey, (but not listed 2007), the tree is not known to be in cultivation beyond North America.
