''Ulmus'' 'Fastigiata Glabra'

Ulmus
Cultivar 'Fastigiata Glabra'
Origin Späth nursery, Berlin, Germany

The elm cultivar Ulmus 'Fastigiata Glabra' was distributed by the Späth nursery, Berlin, in the 1890s and early 1900s as U. montana fastigiata glabra. Späth used U. montana both for wych elm and for U. × hollandica hybrids like 'Dampieri',[1] so the name does not necessarily imply a wych elm cultivar. A specimen in the Royal Botanic Garden Edinburgh was determined by Melville in 1958 as a hybrid of the U. × hollandica group (he called it U. glabra × U. carpinifolia [:U. minor ] × U. plotii [:U. minor 'Plotii' ]).[2] The cultivar did not appear in Späth's 1903 catalogue.

Not to be confused with U. montana fastigiata, Exeter Elm.

Description

Späth's name implies that when young, at least, the tree had an upright form and smooth leaves.

Pests and diseases

Not known. Some examples of the U. × hollandica group possess a moderate resistance to Dutch elm disease.[3]

Cultivation

One tree was planted in 1898 as U. montana fastigiata glabra at the Dominion Arboretum, Ottawa, Canada.[4] Three specimens supplied by Späth to the RBGE in 1902 as U. montana fastigiata glabra may survive in Edinburgh, as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm);[5] the current list of Living Accessions held in the Garden per se does not list the plant.[6] A largish-leaved glabrous elm on The Mound, Edinburgh (2016) matches the 1958 RBGE herbarium leaf-specimen of U. montana fastigiata glabra (see External links below) and may be an example of the cultivar.
