Princeton (elm cultivar)

From Wikipedia, the free encyclopedia

Ulmus americana




Cultivar
Princeton Elm
Origin
Princeton, USA

The Princeton Elm is a cultivar of the American Elm (U. americana) originally selected in 1920 by a New Jersey grower for its landscape qualities. In 1932 many examples of this cultivar were planted along Washington Road and another road in Princeton, and most of these trees survive to this day [1] unaffected by disease. Testing in laboratory conditions by the United States Department of Agriculture (USDA) in 1992-1993 revealed that this cultivar has considerable resistance to Dutch elm disease; consequently, it has been raised for commercial sale again on both sides of the Atlantic. In 2006 it was selected by HRH The Prince of Wales to create an avenue from his residence Highgrove House to the Golden Bird statue at the boundary of the garden. It also has been chosen to replace elms killed by disease along Pennsylvania Avenue in front of the White House.

NB. The original Princeton Elm, which grew in Princeton Cemetery and was estimated to be over 150 years old, was felled in April 2005 after suffering 60% dieback, attributed by some accounts to Dutch Elm Disease [2].
