From Wikipedia, the free encyclopedia
The American Elm Ulmus americana cultivar 'Klehmii' was first marketed by the Naperville Nurseries [3], Naperville, Illinois, in 1929. Distinguished by its shapely, vase form, it was cloned from a tree growing at Arlington Heights by Mr Charles Klehm, proprietor of the Charles Klehm & Son nursery [1] [2]. It is not known whether the tree remains in cultivation.
