Pacific Sunset Maple

Botanical Name: Acer x truncatum ‘Warrenred’

Alternate Name: Warrenred Pacific Sunset Maple

The Pacific Sunset Maple is a moderately fast-growing, small to medium sized, deciduous maple. It grows to a height of 30 feet and a width of 25 feet. It is rounded to pyramidal in shape, with a delicate branching structure and an upright growing habit. This tree is planted for its radiant fall color, as well as its adaptability to both hot and cold conditions.

This maple tree is a hybrid developed from crossing the Shantung maple (Acer truncatum) with the Norway maple (Acer platanoides). This cross gives the Pacific Sunset Maple, also known as Acer truncatum ‘Warrenred,’ the best attributes from both parents. The shorter height, shiny dark green leaves, enhanced fall color and drought resistance comes from Acer truncatum. The adaptability to different environments, the thicker trunk caliper, faster growth rate, and larger leaves all come from Acer platanoides

The Pacific Sunset Maple develops yellowish-green flowers in spring before the foliage growth. These blooms are pretty, providing a modest display. They are followed by 1.5 in. to 2 in. samaras. The leaves are moderately sized and an attractive, shiny deep green with jagged lobes. True to its name, the leaves of the Pacific Sunset Maple transform in the autumn for an amazing performance of yellow, orange, and red fall colors.
