The American elm cultivar Ulmus americana 'Fiorei' was raised by the Charles Fiore Nurseries, Prairie View, Illinois, before 1949, and first listed as 'Fiorii', Fiore Elm, without description. [1] [2] It is no longer listed by the company. [3]
The tree has a narrow form with dense, heavy foliage and a smooth bark. [4]
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 , [5] and highly preferred for feeding by the Japanese beetle Popillia japonica [6] [7] in the United States. U. americana is also the most susceptible of all the elms to verticillium wilt. [8]
Only one tree is known to survive in North America (see Accessions); the tree is not known to have been introduced to Europe or Australasia.
