Mature Jefferson elm
In 2005, Jefferson Elm was jointly released by the
National Park Service (NPS) and the U.S. National Arboretum. Click Here.
It is a true American Elm planted in
the early 1930's on the Mall in Washington D.C. Jefferson has a 70 year proven history of
being free of problems, including D.E.D., while thousands of other elms
within 1 mile have contracted the disease.
I asked one of the D.C. grounds
Horticulturists why they don't plant other tree species. I was told they
do, but elms create a summer comfort level that no other tree can equal.
Elm attributes are:
- High shade with good visibility
under the usually wide canopy.
- Fast sturdy growth with minimum
wind and ice damage.
- Ability to take high compaction
soils, wet and dry.
- Very strong limb attachment and
- Grass grows under elms better
than almost all other trees.
- Roots stay underground and seem
to grow around and/or below solid objects like concrete sidewalks
and other structures instead of breaking them.
- Excellent recovery from ice and
Basically, I was told that without the shade of the
American Elm's, the tourists could hardly survive the summer heat in our
is the Washington Elm. It is planted by the Jefferson Memorial, and is
one that is being evaluated for possible release. The gentleman in the
blue coat is Dr. Denny Townsend. I had the privilege of him showing me
the different elms in his research plots and on the Mall in D.C. He is
also responsible for about 10 cultivars of red maples, several hybrid
elms, several lacebark elms and others. Thanks Dr. Townsend.
