Origin	New York, USA

Ulmus parvifolia 'A. Ross Central Park' (selling name Central Park Splendor) is a Chinese elm cultivar that is probably the hardiest in cultivation and was patented in 1989 by David F. Karnosky. ^[1] The original tree, planted in 1865 by James Hogg, ^{[2] [3]} grew near the entrance to Central Park, at the junction of Fifth Avenue and 72nd Street on the Upper East Side of Manhattan in New York City, and died in the 1990s aged over 120 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

Central Park Splendor is a medium-size tree rarely exceeding 13 m (43 ft) 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. ^[4]
