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.
