Acer grosseri var. hersii d.w. (Green Barked Maple, Hersii Maple) is a variety of maple tree that belongs to the Aceraceae family. It is native to China and is appreciated for its unique green bark coloration, which sets it apart from other maples.
The Hersii Maple is a deciduous tree that typically reaches a height of 20 to 30 feet (6 to 9 meters) with a similar spread. It has an upright, rounded crown and a moderate growth rate. The leaves of this tree are palmate with three to five lobes, and they are usually 2 to 4 inches (5 to 10 centimeters) long. The foliage emerges green in spring, turns vibrant shades of yellow, orange, or red in the fall, and eventually drops in winter.
One of the distinguishing features of the Hersii Maple is its bark. The bark is smooth and starts off as a green color, which eventually matures to a grayish-green or grayish-brown hue as the tree ages. This unique green bark adds visual interest to the landscape throughout the year.
The Hersii Maple prefers well-drained soil and can tolerate a range of soil types, including clay, loam, and sand. It thrives in full sun to partial shade conditions and is adaptable to various climates. It is hardy in USDA hardiness zones 4 to 8.
In spring, the Hersii Maple produces clusters of small, yellowish-green flowers, which are followed by winged samaras. These samaras mature in autumn and can be dispersed by the wind.
The Hersii Maple is often utilized as an ornamental tree for its distinctive green bark, attractive foliage, and overall aesthetic appeal. It is commonly planted as a specimen tree or in groupings to enhance the visual impact of landscapes and gardens. Its smaller size makes it suitable for smaller yards or urban environments.
