US }} The putative American Elm cultivar Ulmus americana 'Burgoyne' was grown at the Arnold Arboretum until removed in 1988. The tree was raised from seeds of the Burgoyne Elm, grown for the town of Weston, Massachusetts, in 1965. The name of the tree was first noted in records of the Plant Sciences Data Center of the American Horticultural Society,[1] but is not formally recognized as a valid cultivar. DescriptionNot available. Pests and diseasesNo specific information available, but the species as a whole is highly susceptible to Dutch Elm Disease and Elm Yellows; it is also moderately preferred for feeding and reproduction by the adult Elm Leaf Beetle Xanthogaleruca luteola [2], and highly preferred for feeding by the Japanese Beetle Popillia japonica [3] [4] in the United States. U. americana is also the most susceptible of all the elms to verticillium wilt.[5]CultivationIt is not known whether the tree remains in cultivation in Weston or elsewhere.
