A medium-size tree with an initially ascending, pyramidal crown and a good upright central leader. Mature trees have an oval crown and grow to a height of 6 to 10 m. The grey-green bark is smooth. The relatively small leaf is oval to elongated-ovate and glossy dark green. In autumn it turns an attractive red to dark wine red. Unlike many other Elms, ‘Frontier’ blossoms in September and not in spring. The tree originated as a hybrid between Ulmus minor and Ulmus parvifolia. The latter is an Asian species that is evergreen in milder climates. Ulmus parvifolia naturally has a very strong resistance to Dutch elm disease. To a certain extent, ‘Frontier’ has inherited this resistance. Its oval crown shape makes it suitable as an avenue tree or street tree.
