Did you know?
1. The Siberian Elm is extremely susceptible to illness and has very brittle wood. The
brittleness of the wood results in damage during storms and under the weight of ice.
2. The Siberian Elm is the hardest elm, and originates from East Asia.
3. The Siberian Elm was once planted as an alternative to the American Elm because the
American Elm was being affected by Dutch Elm’s disease, but the Siberian Elm is resistant
to it. However, it has since fallen out of popularity due to its brittle wood.
