The American Elm U. americana cultivar Independence was raised by Eugene B. Smalley and Donald T. Lester at the University of Wisconsin from a cross between the American Elm cultivar Moline and American Elm W-185-21, to become one of the six clones forming the American Liberty series. However, it has proven only moderately resistant to Dutch elm disease after inoculation with the causal fungus, and it is also susceptible to Elm Yellows.
