Acer negundo d.w. (Boxelder Maple, Manitoba Maple, Ash-leaved Maple)

Acer negundo d.w. (Boxelder Maple, Manitoba Maple, Ash-leaved Maple)  is a fast-growing deciduous tree native to North America. It is often considered a pioneer or colonizing species and is known for its adaptability to various environmental conditions.

The Boxelder Maple typically reaches heights of 12 to 24 meters (40 to 80 feet) with a spread of 9 to 15 meters (30 to 50 feet) at maturity. It has a relatively short lifespan compared to other maples, typically living up to 30 to 60 years.

The leaves of the Boxelder Maple are compound, consisting of three to seven leaflets. The leaflets are elongated and have serrated margins. The color of the leaves can vary, ranging from bright green to a bluish-green hue. In some instances, the leaves may turn yellow in the fall, but they are not known for significant fall coloration.

In early spring, the Boxelder Maple produces clusters of small, greenish-yellow flowers. The flowers are not particularly showy. Following the flowers, the tree develops winged samaras, which are paired seeds with papery wings. These samaras are often present on the tree throughout the summer and early fall before being dispersed by wind.

The Boxelder Maple is known for its tolerance of different soil types and growing conditions. It can thrive in wet areas, including floodplains and along riverbanks, as well as in drier upland sites. It can also adapt to both full sun and partial shade. However, it may become more susceptible to disease and pests in stressful conditions or when planted in poor soil.

It's worth noting that the Boxelder Maple has a reputation for being relatively short-lived and can become weedy in some regions, spreading through its winged seeds. For these reasons, it may not be as popular as other maple species for ornamental planting.
