| 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
'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
In trials 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
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
- Ulmus americana var. molinensis: Bailey & Bailey, Hortus Second 746, 1941.
Hybrid cultivars
'Moline' was crossed with American Elm W-185-21 to create the moderately disease-resistant cultivar 'Independence'.
