Acer negundo subsp. mexicanum is a rapidly growing tree that reaches heights of approximately 15 meters. It features a broad, spreading canopy and has bright green leaves that can grow up to 20 centimeters in length, typically consisting of three leaflets with distinctive red petioles and greyish stems. In the fall, the foliage transitions to a yellow hue. This species produces yellowish-green flowers in the spring, with male and female blossoms found on separate trees.
