''Ulmus'' × ''hollandica'' 'Dampieri'

Ulmus × hollandica 'Dampieri'
'Dampieri', Groningen.
Hybrid parentage U. glabra × U. minor
Cultivar 'Dampieri'
Origin Europe

The hybrid elm cultivar Ulmus × hollandica 'Dampieri', one of a number of cultivars arising from the crossing of the Wych Elm U. glabra with a variety of Field Elm U. minor, is believed to have originated in continental Europe. It was first marketed in the Low Countries in 1853,[1] and was originally identified as Ulmus campestris var. nuda subvar. fastigiata Dampieri Hort., Vilv. by Wesmael.[2]

Description

A fastigiate, conical tree with upright branches bearing tough, ovate leaves < 8 cm long, densely clustered on short, glabrous shoots.[3][4]

Pests and diseases

The tree is susceptible to Dutch elm disease.

Etymology

The tree may be named after the explorer and botanist William Dampier (1651–1715) from East Coker, Somerset, though given its European heritage and 19th century introduction, it is more likely that 'Dampier' was a continental nurseryman from that period.

Cultivation

'Dampieri' was commonly planted in towns in continental northern Europe during the latter half of the 19th century.[5] It was marketed in the 19th century as U. montana fastigiata Dampieri by the Späth nursery of Berlin[6] and by the Ulrich nursery of Warsaw.[7] The tree was introduced to the Dominion Arboretum, Ottawa, Canada in 1896 as U. montana fastigiata (syn. U. montana fastigiata Dampieri).[8] Three specimens supplied by Späth to the Royal Botanic Garden Edinburgh in 1902 as U. montana fastigiata Dampieri may survive in Edinburgh as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm).[9] It appeared as U. montana Dampieri, 'Dampier's Pyramidal Elm', in the 1902 catalogue of the Bobbink and Atkins nursery, Rutherford, New Jersey,[10] and as U. pyramidalis de Dampierre, 'Dampierre's pyramidal elm', in the 1904 catalogue of Kelsey's, New York,[11] and remains in cultivation at the Morton Arboretum.

J. F. Wood in The Midland Florist and Suburban Horticulturist (1851) described a round-headed U. Pyramidalis (an early synonym of 'Dampieri') acquired from the Continent, with "broad, dense, distinct foliage" and similar in form to Lombardy Poplar, but "far preferable" for avenue planting.[12] The early date, however, makes an identification with 'Dampieri' doubtful.

Notable trees

Now a rarity in the UK; the TROBI Champion grows at St George's Road, Lambeth, London, measuring 15 m high by 48 cm d.b.h. in 2003.[13]

Synonymy

Forms

A golden form, 'Dampieri Aurea', of much the same shape and size, is also known as Ulmus × hollandica 'Wredei'.[14]
