Ulmus minor 'Biltii'

Ulmus minor 'Biltii'
SpeciesUlmus minor
Cultivar'Biltii'
Originde Bilt, Netherlands

The Field Elm cultivar Ulmus minor 'Biltii' was selected by Bernard Groenewegen en Zoon (Groenewegen & Son) at his nursery in de Bilt, Netherlands, possibly from French seedlings, and identified in his catalogue of 1921–22 as U. campestris Biltii.[1] Green (1964) confirmed the field elm identification.[1]

Description

'Biltii' has a compact, pyramidal crown, not unlike the Cornish Elm, with crowded, dark green and nearly round leaves. The tips of the younger shoots are tinged purplish-bronze, contrasting with the yellowish-green emergent leaves.[1][2]

Cultivation

No specimens are known to survive. In 2025 Brighton and Hove City Council listed an elm in Benfield Way, Hove, by this name, without provenance information,[3] though its less rounded leaves have more vein-pairs and longer petioles than the 1955 'Biltii' herbarium specimen from Lombarts Nurseries, Zundert.[2]

Synonymy

  • Ulmus campestris 'Biltil': Pierre Lombarts' Royal Nurseries (Zundert, Netherlands) catalogue of 1959-60, p. 83. Misspelling.
