How to Identify an American Sweetgum Tree: Bark, Leaves, and Other Features
The American sweetgum tree, scientifically known as Liquidambar styraciflua, is a beautiful and versatile tree native to North America. With its unique star-shaped leaves and distinctive bark, the American sweetgum is a popular choice for landscaping and urban planting. In this article, we will explore how to identify an American sweetgum tree based on its bark, leaves, and other key features.
Bark
One of the most noticeable features of the American sweetgum tree is its bark. The bark of a mature sweetgum tree is deeply furrowed and divided into narrow ridges. The ridges are arranged in a somewhat diamond-shaped pattern, giving the tree a distinct appearance.
The color of the bark can vary depending on the age of the tree. Younger trees may have smoother bark that is light gray or brown in color, while older trees tend to have darker, rougher bark with a more pronounced diamond pattern.
When identifying an American sweetgum tree based on its bark, look for these key characteristics:
– Deeply furrowed bark
– Diamond-shaped ridges
– Variable colors ranging from light gray to dark brown
Leaves
The leaves of the American sweetgum tree are perhaps its most iconic feature. The leaves are star-shaped with five to seven pointed lobes that radiate from a central point. The edges of the leaves are serrated, adding to their distinctive appearance.
During the fall season, the leaves of the sweetgum tree turn vibrant shades of red, orange, and yellow, creating a stunning display of autumn color. In addition to their shape and color, the leaves also have a strong fragrance when crushed, often described as spicy or aromatic.
