About
Acer Pacific Sunset ('Warrenred') is a deciduous hybrid maple, resulting from a cross between A. truncatum and A. platanoides. This tree typically reaches heights of 8 to 9 meters and develops a well-defined, open, rounded crown. Its large, deeply-lobed leaves are a glossy green during the growing season, transforming into a vivid display of yellow, orange, and red hues in the fall.
