Cultivar 'Morden'

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.

Contents

Description

Fast-growing and ultimately large, it has been described as "rather coarse".

Pests and diseases

The tree is not known to have a resistance to Dutch elm disease (see Cultivation). Its tolerance of Elm Leaf Beetle Xanthogaleruca luteola, and Elm Yellows is unknown.

Cultivation

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.
