Pacific Sunset maple (Acer truncatum x A. platanoides 'Warrenred') is a deciduous tree that is commonly used as a shade tree and as an ornamental tree in landscapes. It is a hybrid between the Shantung maple and the Norway maple, and can grow up to 25 to 35 feet (7.5 to 10.5 meters) tall and 20 to 25 feet (6 to 7.5 meters) wide.
The tree has an oval to rounded habit with a dense, compact canopy, and produces small, yellow flowers in early spring that are followed by winged fruit in summer. Its foliage is a glossy green color throughout the growing season, turning a striking blend of orange, red, and purple in the fall. The Pacific Sunset maple has a smooth gray bark when young, which eventually develops some furrows and fissures as the tree matures.
Pacific Sunset maple is known for its excellent fall color, its adaptability to a range of soil types and environmental conditions, and its resistance to pests and diseases. It is also tolerant of urban pollution and drought
