The American Elm Ulmus americana cultivar ‘Independence’ was raised by Eugene B. Smalley and Donald T. Lester at the University of Wisconsin–Madison from a crossing of the American Elm cultivar Moline and American Elm clone W-185-21 to become one of the six clones forming the American Liberty series and the only one to be patented (U. S. Plant Patent 6227).
