Origin England

The Davey Elm, Ulmus × hollandica 'Daveyi', is an English hybrid cultivar of unknown specific origin, generally restricted to the valleys of Cornwall. Its apparent south-west England provenance, along with its foliage and habit, suggest that it may be a hybrid of Wych Elm and Cornish Elm.[1][2]


The wide-spreading, irregular branches support pendulous branchlets. The leaves are comparatively small, rarely exceeding 6 cm in length by 5 cm wide, with a glabrous upper surface.[3][4][5] Photographs often show this tree in its windswept coastal form; inland its shape resembles more closely its putative Wych Elm parent, though with a denser crown.[1]

Pests and diseases[edit]

The tree is susceptible to Dutch elm disease.


A number of mature specimens are known to survive in south-west England, notably around Gulval, Newquay, the Roseland and St Kew in Cornwall.[1][6] The tree is not known to have been introduced to North America or Australasia, and is not in commerce in the UK.

Notable trees[edit]

The UK TROBI Champion grows in woodland behind Lancaster Avenue at Goodrington; when last measured in 2004 it was 22 m high by 100 cm d.b.h..[7] Other fine specimens can be found at Trenance Farm, St Newlyn East, Newquay.

The Davey Elm was named by Augustine Henry for Frederick Hamilton Davey (1868-1915), Cornish botanist and author of the Flora of Cornwall, first published in 1909 and reprinted in 1978.[5]
