Ross Central Park' = {{tdes|Central Park Splendor|caps}}™ | origin = New York, USA }} The Chinese Elm cultivar Ulmus parvifolia 'A. Ross Central Park' (selling name {{tdes|Central Park Splendor|caps}}™) is probably the hardiest in cultivation and was patented in 1989 by David F. Karnosky.[1] The original tree grew near the entrance to Central Park at the junction of Fifth Avenue with 72nd Street, and died in the 1990s aged over 100 years. The cloning project was initiated in 1976 by the Arthur Ross Foundation, and executed by the School of Forestry and Wood Products, Michigan Technological University, Houghton. Description{{tdes|Central Park Splendor|caps}} is a medium-size tree rarely exceeding 13 m in height, with a broad, rounded crown. The leaves are glossy green, turning yellow in autumn. The mottled bark, its colour ranging from greyish orange to greyish brown, is considered comparatively dull by some.[2]Pests and diseasesThe species and its cultivars are highly resistant, but not immune, to Dutch elm disease, and completely unaffected by the Elm Leaf Beetle Xanthogaleruca luteola.[3] Cultivation{{tdes|Central Park Splendor|caps}} is not known to be in cultivation beyond North America.Synonymy
