Ulmus parvifolia 'A. Ross Central Park'

Ulmus parvifolia 'A. Ross Central Park`' (selling name ') is a Chinese elm cultivar that is probably the hardiest in cultivation and was patented in 1989 by David F. Karnosky. The original tree grew near the entrance to Central Park, at the junction of Fifth Avenue and 72nd Street in the Upper East Side of Manhattan in New York City, 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.
