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' is said to have been first described as 'Variegata' by Wesmael in Bull. Fed. Soc. Hort. Belg. 1862: 390, 1863.[1] Augustine Henry, however, citing Loudon Arb. et Frut, Brit. iii. (1838), listed an U. nitens var. variegata cultivated in Chiswick, matching the description of 'Variegata' and dating from 1838.[2]

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.[3][4] '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.

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'.[5]

Pests and diseases

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

Cultivation

In Australasia and North America, where 'Variegata' is commonly cultivated and where a number of mature specimens survive (see under Accessions), the tree is known as Silver Elm [6][7] or Tartan Elm.[8] The tree also remains in commercial cultivation in Europe.

Notable trees

A notable specimen of Variegated Field Elm grew at Leek Wootton, Warwickshire.[9] 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.[10] '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.[11] A specimen in Portland, Oregon, has been designated a 'Heritage Tree'.[12]
