''Ulmus minor'' 'Argenteo-Variegata'

Ulmus minor

'Argenteo-Variegata', Benalla Botanic Garden, Australia
Cultivar 'Argenteo-Variegata'
Origin Europe

The Field Elm cultivar Ulmus minor 'Argenteo-Variegata' or simply 'Variegata', known in Australasia and North America as Silver Elm [1][2] or Tartan Elm,[3] is said to have been cultivated in France from 1772. Green noted that variegated forms of Field Elm "arise frequently, and several clones may have been known under this name".[4] Dumont de Courset (1802) listed an U. campestris var. glabra variegata,[5] Loudon (1838) an U. nitens var. variegata, and Wesmael (1863) an U. campestris var. nuda microphylla variegata.[6][7]

'Variegata' is not to be confused with the variegated English Elm cultivar, U. minor 'Atinia Variegata', which has the broader, almost orbicular leaves of the type.

Description

U. minor 'Variegata'

The tree's foliage is randomly blotched and speckled with creamy white, the colour of the leaves on the same tree ranging from almost completely cream to totally green.[8][9]

Etymology

As the blotching and margination of the foliage may appear more silver than cream, the cultivar is sometimes listed as U. minor 'Argenteo-Variegata'.[10]

Pests and diseases

The cultivar is as susceptible to Dutch elm disease as the species.

Henry cited Loudon's report that 'Variegata' was cultivated in Chiswick in the early 19th century.[11] The tree remains in commercial cultivation in Europe, and is commonly cultivated in Australasia and North America, where a number of mature specimens survive (see under Accessions).

Notable trees

A notable specimen of Variegated Field Elm grew at Leek Wootton, Warwickshire.[12] In the Netherlands, one tree, known as the Rococo Iep (:Elm) grows at Houten, next to the old church. In Australia, several trees planted in 1897 stand in Geelong Botanic Gardens, Victoria.[13] 'Atinia Variegata' is also found among the elms lining the Avenue of Honour at Ballarat, while approximately 50 trees grow at The Nook, Sunbury. There are two mature trees in the Royal Tasmanian Botanical Gardens, Hobart.[14] A specimen in Portland, Oregon, has been designated a 'Heritage Tree'.[15]
