Description
Robertson stated that 'The Black Irish Elm' took its name from its dark chestnut-coloured young shoots, and that it made a slender, erect tree when old.[1] Loudon described the tree as of moderate size, with a spreading habit like wych elm, but comprising rather irregular, contorted branches bearing much smaller, more rugose leaves,[3] of a much deeper green than the species.[9] Späth's U. montana nigra, by contrast, was "large-leaved, with dark-green foliage".[7]
Cultivation
Loudon reported that the tree ripened seed in Ireland.[3] Robertson sent specimens to the National Botanic Gardens, Glasnevin, and to Edinburgh.[1] It was also grown in the 19th century in the Horticultural Society's Garden at Chiswick[1] and the Royal Victoria Park, Bath, at the western end of the Royal Avenue.[9] U. montana nigra was introduced to the Dominion Arboretum, Ottawa, Canada, probably from Späth, in 1899.[10] The tree is not known to have been introduced to Australasia, nor is it known to be in commerce.
