Botanical Name

ACER x freemanii 'Armstrong'

Plant Common Name

Freeman's Maple

General Description

Freeman's maple is a large to medium-sized deciduous tree resulting from the cross between two North American natives, Acer rubrum (red maple) and Acer saccharinum (silver maple). This vigorous hybrid boasts many cultivars, the best of which combine the toughness of silver maple with the brilliant fall color of red maple. The cultivar ‘Armstrong’ has a columnar shape and upright branching. The leaves closely resemble its silver maple parent with blunt lobes and undependable fall color from yellow to orange. It is a fast grower with unremarkable flowers.

Freeman maple prefers full sun and can tolerate a wide range of soil types. It is best planted as a shade tree in residential or high-traffic public areas and may also make a suitable street tree. Some cultivars may be hardier than others depending on their origin.
