| Species | Ulmus americana |
| Cultivar | 'Patmore' |
| Origin | Brandon, Manitoba, Canada |
The American Elm cultivar Ulmus americana 'Patmore' was selected and raised by R. H. Patmore from a native tree in Brandon, Manitoba, Canada. It may be synonymous with another cultivar from the same source, known as 'Brandon'. [1]
'Patmore' (or 'Brandon') differs from most American Elms in possessing a pyramidal, as opposed to vase, form. [2]
No other specific information available, but the species generally 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] [7]
The tree is not known to have been cultivated beyond North America.
