'Moline' is distinguished by its narrow but open form, the older branches ultimately horizontal [2].
In trials [3] at the Morton Arboretum, Illinois, the tree was eschewed by the Elm Leaf Beetle Xanthogaleruca luteola. The tree's resistance to Dutch elm disease is not known.
In earlier field trials at Morton, 'Moline' was found to have a relatively fast growth rate, exceeding 7.7 m (25 ft) in height in 10 years. The tree is not known to have been introduced to Europe or Australasia.
'Moline' was crossed with American Elm W-185-21 to create the moderately disease-resistant cultivar 'Independence'.
