Umbraculifera (elm cultivar)

From Wikipedia, the free encyclopedia

The Smooth-leaved Elm U. minor var. minor cultivar Umbraculifera was originally cultivated in Iran. The tree is distinguished by its dense, rounded habit, and was once widely planted in Iran as an ornamental, where it occasionally grew to an enormous size. The tree is indistinguishable from U. minor var. minor in all but shape. It was introduced to Europe in 1878 by Spath, who obtained it from a German gardener in the employ of the Shah, and was subsequently planted along streets in Berlin. Bean (1981) remarked that the tree succeeded well on the continent (Europe) and in eastern North America, but was rarely planted in the UK. The tree is as vulnerable to Dutch elm disease as its siblings.
