Bright Red Fall Color on a Seedless Red Maple Sun Valley Maple is a selected red maple cultivar valued for brilliant red fall color, glossy green summer foliage, and a clean, seedless habit. This male red maple selection provides the classic autumn color homeowners want from a red maple without the heavy samara production that can come from seed-bearing trees. In fall, Sun Valley Maple develops rich red foliage that creates strong curb appeal in front yards, lawns, streetscapes, and large residential landscapes. Its reliable seasonal color, moderate mature size, and tidy habit make it a smart choice where homeowners want shade, structure, and standout autumn beauty in one tree. A U.S. National Arboretum Selection with Strong Landscape Value Sun Valley Maple was introduced by the U.S. National Arboretum and is known as a seedless red maple selection. It is often described as a hybrid between Red Sunset and Autumn Flame, combining strong red fall color with a practical male, seedless habit. The tree develops a broadly oval to rounded canopy with attractive green foliage through the growing season. Its size makes it useful in residential landscapes where a large shade tree is desired but where the scale of some larger red maples may be too much. It is especially valuable for homeowners who want a cleaner maple near lawns, driveways, or high-visibility landscape areas. Ideal for Front Yards, Lawns, Streets, and Driveways Sun Valley Maple works well as a front-yard, lawn, street, or driveway accent, or as a medium-to-large shade tree in sunny landscapes. It gives homeowners the familiar look of a native red maple with improved ornamental consistency and reduced seed mess. Plant it where it has room for a mature canopy. It should not be placed directly under overhead utility lines or squeezed into narrow foundation beds. When given space, Sun Valley Maple becomes a handsome shade tree that provides cooling summer coverage and bold fall color. Cold Hardy, Adaptable, and Less Mess Than Seeded Maples Sun Valley Maple is cold-hardy and adaptable across many landscapes. It grows best in full sun to part shade and prefers moist, well-drained, slightly acidic soil. It can tolerate seasonal wet soil and short dry periods once established, but consistent moisture produces the healthiest growth and best foliage quality. Its seedless nature is one of its strongest landscape advantages. Homeowners who like red maple color but dislike the nuisance of winged seeds will appreciate Sun Valley’s cleaner habit. Like other red maples, it may struggle in very alkaline soils, where chlorosis can cause leaves to yellow. Easy Care with Good Siting and Early Structure Plant Sun Valley Maple in a sunny or lightly shaded location with enough room for its mature spread. Water regularly after planting until the root system establishes, and mulch around the root zone to conserve moisture and protect the trunk from mower and trimmer damage. Young trees benefit from structural pruning to develop strong branch spacing and a balanced canopy. Remove crossing, damaged, or poorly attached branches while the tree is young. With good siting, moisture, and early care, Sun Valley Maple becomes a dependable long-term shade and fall color tree.
