Acer rubrum, commonly called red maple, is a medium-sized, deciduous tree that is native to Eastern North America from Quebec to Minnesota south to Florida and eastern Texas. It typically grows 40-60’ tall with a rounded to oval crown. Quality of red fall color on species plants is variable. Leaves (to 2-5″ long) have 3 principal triangular lobes (sometimes 5 lobes with the two lower lobes being largely suppressed). Lobes have toothed margins and pointed tips. Leaves are medium to dark green above and gray green below. Flowers on a given tree are primarily male or female or monoecious and appear in late winter to early spring (March-April) before the leaves. Fruit is a two-winged samara.

Specific epithet of rubrum meaning red is everywhere in evidence: red flowers in dense clusters in late March to early April (before the leaves appear), red fruit (initially reddish, two-winged samara), reddish stems and twigs, red buds, and, in the fall, excellent orange-red foliage color.

‘Sun Valley’ is a U.S. National Arboretum introduction. It is a male selection that is noted for having a symmetrical ovate crown and exceptional red fall color. It typically grows to 21’ tall over the first 10 years, eventually maturing to as much as 30-35’ tall in ideal growing conditions. It is the result of a cross between A. rubrum ‘Red Sunset’ and A. rubrum ‘Autumn Flame’. Reddish male flowers appear in early spring. No fruit is produced. Medium green leaves (to 4” long). Fall color for this cultivar appears as a brilliant red in late fall.
