Elms are deciduous trees belonging to the genus Ulmus. They are known for their tall, sturdy trunks and broad, spreading canopies. Elms can grow up to 100 feet tall and are often found in temperate regions around the world. Their leaves are typically serrated and turn yellow in the fall. These trees are valued for their shade and aesthetic appeal in urban and rural landscapes. However, many elm species have been affected by diseases like Dutch elm disease, which has significantly reduced their populations in some areas. Despite this, elms remain an important part of many ecosystems.
