Ulmus × hollandica 'Gaujardii'
'Gaujardii' at 3 years
Hybrid parentage	U. glabra × U. minor
Cultivar	'Gaujardii'
Origin	France

The hybrid elm cultivar Ulmus × hollandica 'Gaujardii', one of a number of cultivars arising from the crossing of Wych Elm U. glabra with Field Elm U. minor, was raised by the Gaujard-Rome nursery of Châteauroux, France, in the 1890s as Ulmus Gaujardii and was described in the 1898 Kew Bulletin and Wiener illustrirte Garten-Zeitung.^[1]^[2] It won first prize in the International Horticultural Exhibition in Saint Petersburg, Russia, in 1899 and a silver medal in the Heemstede Exhibition, The Netherlands, in 1925.^[3] From the early 20th century it was distributed by the Späth nursery of Berlin as Ulmus montana Gaujardi,^[4] and in the interwar years by the Boccard nursery of Geneva as Ulmus campestris Gaujardi.^[5] It appeared in Unsere Freiland-Laubgehölze in 1913, but without description.^[6]^[7]

Description

[edit]

A tree of symmetrical upright growth and of great vigour, with the appearance of an arrow. The foliage was of medium size, oval and light green.^[1]^[2] Four photographs of 'Gaujardii' appear in Pépinières Gaujard-Rome et Cie (1930), where the nursery distinguished between medium- and large-leaved forms.^[3] Herbarium specimens suggest that more than one clone has been labelled 'Gaujardii'.^[8]^[9]

Pests and diseases

[edit]

Elms of the U. × hollandica group are susceptible to Dutch elm disease.

Cultivation

[edit]

'Gaujardii' was produced at a rate of 30,000 trees per annum by 1930,^[3] though no specimens are known to survive. There was a specimen at Arnold Arboretum, Massachusetts, in the mid-20th century.

Putative specimen

[edit]

An old U. × hollandica with leaves (unusually for this group) light green all summer and matching the 'Gaujardii' herbarium specimen in The Hague,^[9] stands (2019) by 35 Inverleith Terrace, Edinburgh, near the entrance to Royal Botanic Garden.^[10] An early 20th century photograph shows it fastigiate when young.^[11] Its leaf-shape, samarae, and light suckering confirm its hybridity.
