  • In the 20th century, Dutch elm disease caused American elm trees to be killed off since they were very vulnerable to the pathogen. American elms once used to live up to 200 or more years, but because of this disease, individuals rarely survive beyond 30 years.
  • American elms tend to have twisting upper branches.
  • The American elm is the state tree of Massachusetts and North Dakota. It became the state tree of Massachusetts because General George Washington became commander of the Continental Army beneath an American elm on Cambridge Common in 1775.
