Ulmus pumila, commonly known as the Siberian elm, is a deciduous tree native to northern China, central Asia, and eastern Siberia. This tree is known for its hardiness and ability to grow in challenging conditions. It has been widely planted in locations across the world and is often used as a street tree. Some synonyms for Ulmus pumila include dwarf elm, Asiatic elm, Chinese elm, and Tibetan elm. Despite its popularity, the Siberian elm has been known to be invasive in some areas, leading to concerns about its impact on native ecosystems.
