Iran |
The Field Elm Ulmus minor sensu latissimo cultivar 'Umbraculifera' originated in Iran, where it was once widely planted as an ornamental, and occasionally grew to a great size.
Description
The tree is distinguished by its dense, rounded habit.[1]
Pests and diseases
The tree is as vulnerable to Dutch elm disease as the species; a specimen at the Ryston Hall [5], Norfolk, arboretum, obtained from the Späth nursery before 1914 [2], was killed by the earlier strain of the disease in the 1930s.
Cultivation
The tree was introduced to Europe in 1878 by the Späth nursery in Berlin, which had obtained it from a German gardener in the employ of the Shah of Persia, and was subsequently planted along streets in Berlin.[3][4] Bean remarked that the tree succeeded well on the continent (Europe) and in eastern North America, but was rarely planted in the UK [5]. Introduced to Australia, the tree was marketed in the early 20th century by the Gembrook Nursery near Melbourne and by Searl's Garden Emporium, Sydney, but it is not known whether the tree survives in that country. Despite its susceptibility to the disease, it remains in commercial cultivation in Belgium and the Netherlands.
