The American Elm U. americana Moline is one of the older cultivars, originating as a wild seedling transplanted to Moline in 1903. Propagated from 1916, it was distinguished by its narrow but open form, the older branches ultimately horizontal http://www.virtualplanttags.com/vpt.asp?co=410087&pID=39294&cID=196&r=GIYP. In trials http://www.treelink.org/joa/2003/march/05Miller.pdf at the Morton Arboretum, Illinois, the tree was eschewed by the elm leaf beetle.
