| Origin | Europe |
The Wych Elm cultivar Ulmus glabra 'Gigantea' was listed as U. montana var. gigantea Hort. by Kirchner (1864).[1] A cultivar named U. montana gigantea was distributed by the Späth nursery, Berlin, in the 1890s and early 1900s. It did not appear in Späth's 1903 catalogue.
Green gave a different clone, the Dutch Elm 'Major', as synonym of 'Gigantea'.[2]
Description
Herbarium leaf-specimens show a large orbicular wych elm leaf with a typically short petiole (see External links below).
Pests and diseases
A cultivar of the Wych Elm, 'Gigantea' is susceptible to Dutch Elm disease.
Cultivation
One tree was planted in 1897 as U. montana gigantea at the Dominion Arboretum, Ottowa, Canada.[3] Three specimens supplied by Späth to the RBGE in 1902 as U. montana gigantea may survive in Edinburgh, as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm);[4] the current list of Living Accessions held in the Garden per se does not list the plant.[5]
Accessions
None known.
