Dutch Elm
FAMILY: ULMACEAE
About Dutch Elm at OSU's Landscape Plants site
A hybrid, most likely between smoothleaf elm (U. minor) and Wych elm (U. glabra). A lot of variations exist.
Depending on hybrid origin, height can reach 120’.
Leaves are usually 2.5-4.5” long, smooth above and fuzzy underneath, sometimes only along veins.
Flowers vary; seeds similar to all elms.
Elm trees often get named Dutch by default, lacking the characteristics defining other species. All elms except recent cultivars are susceptible to Dutch elm disease.
Common in Portland.
#46 was planted in the late 19th century. It was condemned to be cut down by the Portland City Council in 1963, but a devoted group of tree lovers saved its life.
#119 has a large witches’ broom, which can be caused by a virus, bacteria, or fungus.
