American Elm
Armstrong Maple

American Elm is fast growing, tall tree with a recognizable and pleasing shape.

It's well suited for urban environments because of its non-invasive roots and ability to grow on harsh sites (quite salt tolerant). American Elm develops a wide, dense canopy that provides shade for many city streets around North America.

The Armstrong Maple has a narrow, upright columnar growth habit. This stunning tree has showy leaves that range from yellow, orange to red in the fall. It is an attractive hybrid of the Red Maple and Silver Maple. It prefers acidic soils and will have some tolerance for drought once mature.

Edward Murray named the Armstrong Maple in 1969 in honor of Oliver M. Freeman of the National Arboretum, who made the first controlled cross between the two species in 1933.
