Armstrong Maple
Korean Maple

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.

The Korean Maple is an ideal accent tree, and is similar in size and shape to the Japanese Maple, but much hardier. The leaves have long, finger-like lobes that turn striking shades of yellow, orange and red in autumn.

It is recommended that pruning be done during the summer after the leaves have fully developed to ensure sap does not "bleed" down the tree.
