Cultivar 'Moline'
Origin Moline, Illinois, USA

The American Elm cultivar Ulmus americana 'Moline' was cloned from a wild seedling transplanted to Moline in 1903 and propagated from 1916 by the Klehm Nurseries, Arlington Heights, IL. [1] [2] Some authorities regard the tree as identical to 'Minneapolis Park'.

Description[edit]

'Moline' is distinguished by its narrow but open form, likened to a Lombardy Poplar, when young, the branches of the older trees ultimately horizontal. The leaves could be exceptionally broad, measuring 15 cm across.[2][3]

Pests and diseases[edit]

In trials [2] 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.

Cultivation[edit]

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 was still in cultivation in 1934, [4] but is not known to have been introduced to Europe or Australasia.

Synonymy[edit]

  • Ulmus americana var. molinensis: Bailey & Bailey, Hortus Second 746, 1941.

Hybrid cultivars[edit]

'Moline' was crossed with American Elm W-185-21 to create the moderately disease-resistant cultivar 'Independence'.
