Thefield elmcultivarUlmus minor 'Silvery Gem' is an ornamental clone raised, asUlmus carpinifolia 'Silvery Gem', before 1965 by P. G. Zwijnenburg of Zwijnenburg nurseries,Boskoop, The Netherlands.[1]
A moderately tall growing shrub, reaching about 3–4 m (9.8–13.1 ft) in 10 years and with rather dense, twiggy branches bearing ovate leaves of a grey-green or silvery colour, especially in the spring, with irregular but conspicuous creamy-white margins.[2] The colouring and variegation are most striking in spring, fading somewhat in summer.[1][3][4]
'Silvery Gem' is not known to be resistant toDutch elm disease,[citation needed] but the low height of the tree may ensure that it avoidscolonization byScolytus bark beetles and thus remain free of infection. It has been noted that shrub-elms are usually less prone to infection.[5]
The clone won a Golden Medal in The Netherlands in the mid-1960s.[1] It remains available from several nurseries in Europe (see below).
