Sun Valley Maple – Acer Rubrum Sun Valley


Acer rubrum ‘Sun Valley,’ or Sun Valley Maple, is a medium-sized deciduous tree known for its uniform shape, vibrant fall foliage, and adaptability to various growing conditions.

Sun Valley Maple, also known as Acer rubrum ‘Sun Valley,’ is a popular cultivar of the native North American Red Maple tree. It is valued for its uniform shape, excellent autumnal colour, and adaptability to a wide range of growing conditions. Sun Valley Maple is a medium-sized deciduous tree that typically reaches a height of 40 to 50 feet (12 to 15 meters) with a slightly smaller spread. It has a symmetrical, oval to rounded crown and a dense branching structure. The leaves of Sun Valley Maple are medium-sized and palmate, consisting of three to five lobes with serrated edges. In spring and summer, the leaves are deep green in colour, providing a lush canopy. During the fall, the foliage transforms into vibrant shades of orange, red, and yellow, creating a stunning display of autumnal colours.
Sun Valley Maple is known for its adaptability to various environmental conditions. This cultivar is versatile in terms of soil adaptability and can tolerate different soil types, including clay, loam, and sandy soils. It grows best in full sun to partial shade but can tolerate some shade as well.
Sun Valley Maple is highly valued for its ornamental value. Its uniform shape and symmetrical crown make it an excellent choice as a shade tree or a specimen tree in landscapes, parks, and residential settings. The vibrant fall foliage adds seasonal interest and can serve as a focal point in the landscape. Sun Valley Maple can also be used in group plantings to create a striking visual effect or to provide shade in larger outdoor spaces.
Sun Valley Maple has relatively low maintenance requirements. It benefits from regular watering, particularly during dry periods, to ensure proper establishment and growth. Mulching around the base of the tree helps retain moisture and control weed growth. Pruning is minimal and generally involves removing dead, damaged, or crossing branches. Regular inspections for common pests and diseases, such as aphids or leaf spot, are recommended to address any issues promptly.
