Description
The tree was described simply as having yellow foliage.
Pests and diseases
No 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,[3] and highly preferred for feeding by the Japanese Beetle Popillia japonica [4][5] in the United States. U. americana is also the most susceptible of all the elms to verticillium wilt.[6]
Cultivation
Young trees are grown in Belgium and London, cloned from a tree (now dead) which grew in Illinois.
