Dutch Elm is a term used to refer to a species of elm tree that originated from the Netherlands. Its scientific name is Ulmus x hollandica. However, over the years, the term Dutch Elm has become associated with a disease known as Dutch Elm Disease. This disease is caused by a fungus and affects the vascular system of elm trees, causing them to wilt and eventually die. Some synonyms for Dutch Elm include European White Elm, Smooth-Leaved Elm, and Common Elm. These synonyms are often used to differentiate between healthy elm trees and those infected with Dutch Elm Disease.
