Cultivar'Gigantea'
OriginEurope

TheWych ElmcultivarUlmus glabra 'Gigantea' was listed asU. montana var.giganteaHort. by Kirchner (1864).[1] AnU. montana gigantea was distributed by theSpäth nursery, Berlin, in the 1890s and early 1900s. It did not appear in Späth's 1903 catalogue.[2] A specimen atKew was judged byHenry to be "not distinct enough to deserve a special name".[3] Both Späth and the Hesse Nursery ofWeener,Germany, supplied it in the 1930s.[4][5]

Green gave a different clone, the Dutch Elm'Major', as synonym of 'Gigantea'.[6]

Description

[edit]

The Kew specimen was a small tree with ascending branches.[3] Herbarium leaf-specimens show a large orbicular wych elm leaf with a typically short petiole.[7]

Pests and diseases

[edit]

A cultivar of theWych Elm, 'Gigantea' is susceptible toDutch Elm disease.

Cultivation

[edit]

One tree was planted in 1897 asU. montana gigantea at theDominion Arboretum,Ottawa, Canada.[8] Three specimens supplied by Späth to theRBGE in 1902 asU. montana gigantea may survive in Edinburgh, as it was the practice of the Garden to distribute trees about the city (viz. theWentworth Elm);[9] the current list of Living Accessions held in the Gardenper se does not list the plant.[10]
