Acer rubrum 'Sun Valley', commonly known as the Sun Valley Red Maple, is a stunning deciduous tree renowned for its vibrant autumn foliage and symmetrical, rounded canopy. This cultivar, a hybrid of the Red Maple, was specifically developed by the U.S. National Arboretum for its exceptional fall colour and resistance to leaf tatter. In the fall, the leaves turn a brilliant, fiery red, creating a spectacular display that can light up any landscape.

At maturity, the Sun Valley Red Maple reaches a height of around 10 to 12 meters and spreads to about 7 to 9 meters, making it an ideal choice for a medium-sized shade tree. The tree's uniform branching and dense foliage provide excellent shade during the summer months. It also features red flowers in early spring, which add to its ornamental value, although they are relatively inconspicuous compared to its fall display.

The Sun Valley Red Maple thrives in a variety of soil types, including clay, loam, and sandy soils, as long as they are well-drained. It prefers slightly acidic to neutral pH levels but can tolerate a range of soil conditions. This tree grows best in full sun to partial shade, requiring at least six hours of direct sunlight for optimal growth and colour development. Its adaptability, low maintenance requirements, and stunning seasonal colour make it a popular choice for urban landscapes, parks, and residential gardens.
