Cultivar 'Jackson'
Origin Wichita, Kansas

The American Elm cultivar Ulmus americana 'Jackson' was cloned from a selection made at Wichita, Kansas, which had reputedly shewn no signs of Dutch elm disease damage at >50 years of age.

Pests and diseases[edit]

The resistance of 'Jackson' to Dutch Elm Disease has not (< 1995) been confirmed by artificial inoculation.[1] The species is highly susceptible to Elm Yellows; it is also moderately preferred for feeding and reproduction by the adult Elm Leaf Beetle Xanthogaleruca luteola [2] [1], and highly preferred for feeding by the Japanese Beetle Popillia japonica [3] [2] [3] in the United States. U. americana is also the most susceptible of all the elms to verticillium wilt.[4]

Cultivation[edit]

Last listed in the Fall 1994 - Spring 1995 catalogue of the now-defunct Arborvillage Farm Nurseries, Holt, Missouri. The tree is not known to have been introduced to Europe or Australasia.
