These include selections of hybrids of Asian or European elms that are resistant to Dutch elm disease. ‘AccoladeTM’ (Ulmus japonica x Ulmus wilsoniana) – displays a handsome, vase-shaped canopy, deep green glossy leaves, and has shown resistance to Dutch elm disease, elm leaf beetle and leafminer. Zone 4. ‘Frontier’ (Ulmus carpinifolia x Ulmus parvifolia) – up to 70’ moderate resistance to elm leaf beetle and high tolerance to elm yellows. Forms a pyramidal rather than vase-shaped crown as it matures. Zone 5. ‘Triumph’ (Ulmus ‘Morton Glossy’) – up to 70’, lustrous, dark green foliage in summer. Yellow fall color maintains excellent disease and pest resistance as well as good drought tolerance, making it a great choice for tough, urban planting sites. Zone 4.
