BigDaddyData.Com: Massachusetts American Elm

The American Elm was adopted as the official tree March 21, 1941, to commemorate the fact that General George Washington took command of the Continental Army beneath one on Cambridge Common in 1775. It is a large tree, with gray flaky bark. When growing in the forest it often attains a height of 120 feet, but in the open it is wide-spreading and of lesser height. The leaves are oval, and dark green, turning to a clear yellow in the autumn.

The American Elm, like most elms, has been severely afflicted by Elm Disease.
