With its fiery autumn colour and compact size, 'Sun Valley' is a popular medium-sized, deciduous tree whose crown develops into an oval to rounded shape. The young foliage emerges reddish-green before maturing to bright green in summer, and clusters of tiny red flowers adorn the bare branches in early spring. The classic 3-5 lobed, maple-shaped leaves turn brilliant shades of orange and red in October, the colour being more vibrant and lasting longer than other varieties when grown in neutral to acid soils. An excellent landscape tree option.
