From Wikipedia, the free encyclopedia
The possible Siberian Elm Ulmus pumila hybrid cultivar 'Kansas Hybrid' was raised by the Kansas Nursery Co., Salina, Kansas in the 1920s from a seedling exhibiting hybrid characteristics, and maintained by grafting. Described as having an upright branching habit, and dark, shiny leaves the same size as U. americana [1]. Fast growing, it was also reputed to be cold and drought resistant, but had not (by 1995) been widely tested for resistance to Dutch elm disease. The inclusion of the word "hybrid" is considered to render the cultivar name invalid [2]. The tree is not known to have been introduced to Europe or Australasia.
