Description
'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. The small leaves are grass-green in colour, turning a dull red in autumn. The samarae too are reddish in colour.[1]
Pests and diseases
The species and its cultivars are highly resistant, but not immune, to Dutch elm disease, and unaffected by the Elm Leaf Beetle Xanthogaleruca luteola.[2]
Cultivation
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.
Accessions
North America
gollark: The problem is worse in a spæce future, because of the fact that spaceships have lots of kinetic energy.
gollark: Hey, humans could TOTALLY mess up in that way too!
gollark: *But* some single humans could... probably break civilization.
gollark: Not entirely, no.
gollark: As technology improves this will probably get even more problematic as individual humans get able to throw around more energy to do things.
