This summer saw the removal of the last Malus tschonoskii on campus. As part of our mission to display great plants for Delaware Valley gardeners, we trial new introductions and cultivars of plants. Beginning in the 1980s, Scott Arboretum participated in the National Crabapple Evaluation Program led by Professor Les Nichols of Penn State University.  This program evaluated readily available crabapple cultivars in various locations throughout the United States based mainly on disease resistance and aesthetic autumn appeal.
