From Wikipedia, the free encyclopedia
The American Elm Ulmus americana cultivar 'Morden' [2] was selected by the Dominion Experimental Farm, Morden, Manitoba, in 1939 on account of its ability to withstand severe ice storms without breakage. Fast-growing and ultimately large, it has been described as "rather coarse". The tree was first marketed by the Patmore Nurseries, Brandon, Manitoba, circa 1948 [1]. A specimen planted in the Longenecker Gardens at the University of Wisconsin-Madison Arboretum [2] in 1956 had died by 1974 "probably from Dutch elm disease"; no others are known to remain in cultivation.
