Elm/Ulmus – St. Croix™ American Elm

St. Croix™ elm is a new and distinct American elm with good tolerance to Dutch elm disease. With a grand, vase shape and an open, spreading canopy, St. Croix™ promises to revitalize this well-loved shade tree. Its summer foliage is a beautiful dark green with fall foliage turning a wonderful yellow. The selection is a clone from a tree in Minnesota that survived in a stand of Dutch Elm Disease-infected elms for over 35 years. In testing at the University of Minnesota, St. Croix shows very good Dutch Elm Disease tolerance in repeated field trials with controlled inoculation.
