Ailanthus altissima, commonly known as the tree of heaven, is a fast-growing deciduous tree native to China. It can reach heights of 50 to 80 feet and is characterized by its large, pinnately compound leaves and clusters of small, yellow-green flowers. The tree is often found in urban areas and disturbed sites due to its ability to thrive in poor soil conditions. This species is known for its invasive nature, spreading rapidly and outcompeting native plants. Its seeds can be dispersed by wind, and it can also reproduce through root suckers. While it provides some ecological benefits, such as shade, it can disrupt local ecosystems.
