| Species | Ulmus parvifolia |
| Cultivar | 'Ohio' |
| Origin | US |
The Chinese elm cultivar Ulmus parvifolia 'Ohio' was raised by A. M. Townsend at the USDA National Arboretum, [1] and released in 1992.
'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. [3]
The species and its cultivars are highly resistant, but not immune, to Dutch elm disease, and unaffected by the elm-leaf beetle ( Xanthogaleruca luteola ). [4]
Initially marketed by Princeton Nurseries, near Kingston, New Jersey (but not listed 2007), the tree is not known to be in cultivation beyond North America.
