Description
The tree is narrowly vase-shaped with larger and heavier leaves.
Pests and diseases
The clone's resistance to Dutch Elm Disease is not known, but the species is highly susceptible to the disease and Elm Yellows; it is also moderately preferred for feeding and reproduction by the adult Elm Leaf Beetle Xanthogaleruca luteola [1], and highly preferred for feeding by the Japanese Beetle Popillia japonica [2] [3] in the United States. U. americana is also the most susceptible of all the elms to verticillium wilt.
Cultivation
'Littleford' was marketed by the Sherman Nursery, Charles City, Iowa, as late as 1957, but is no longer listed by that emporium or any other. The tree is not known to have been introduced to Europe or Australasia.
