Ulmus americana 'St Croix' PP20,097
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 DED-infected elms for over 35 years. In testing at the University of Minnesota, St. Croix shows very good DED tolerance in repeated field trials with controlled inoculation.
