Cultivar 'Sowerbyi'
Origin England

The Field Elm cultivar Ulmus minor 'Sowerbyi', commonly known as the Sowerby Elm, was described (as Ulmus nitens var. sowerbyi Moss) by Moss [1] in The Cambridge British Flora 2: 90. 1914. The tree, once referred to as the Norfolk Elm by Smith, was commonly found in the hedgerows and woods of Norfolk, Cambridgeshire, and Huntingdonshire in the early 20th century before the advent of Dutch elm disease.[1]

Description[edit]

A smaller tree than 'Hunnybunii', the branches shorter and the upper ones very tortuous; leaves smaller and acute.[2] The obovate to elliptical fruits are also smaller than 'Hunnybunii'. [1] Melville considered it a hybrid of 'Coritana'. [3]

Pests and diseases[edit]

Though susceptible to Dutch Elm Disease, field elms produce suckers and usually survive in this form in their area of origin.

Cultivation[edit]

No mature specimens are known to survive.
