Ulmus minor
Cultivar 'Dicksonii'
Origin England

The Field Elm cultivar Ulmus minor 'Dicksonii', commonly known as Dickson's Golden Elm, is a yellow-leaved tree raised in Chester in 1900 by Dickson's Nursery, which marketed it as the 'Golden Cornish Elm'.[1] 'Dicksonii' was first distributed in the autumn of 1907,[2] and was later granted the Award of Garden Merit (AGM) by the Royal Horticultural Society in 1969.

Description

Of free and upright growth,[3] but slow growing,[4] the leaves are "a fine yellow colour, said to last till autumn".[1]

Pests and diseases

'Dicksonii' is susceptible to Dutch elm disease.

Cultivation

The horticulturalist Christopher Lloyd used the tree in his celebrated long herbaceous borders at Great Dixter Gardens, Northiam, East Sussex.[5] Though now very rare in the UK, the cultivar is still much planted in Australia. In the USA, 'Dicksonii' is sold as Ulmus procera 'Aurea' by nurseries in Oregon.[6]

Notable trees

Among the few survivors in the UK are two in Peasholm Park, Scarborough, North Yorkshire, rediscovered in 1994 during a National Tree Register audit of the trees in Peasholm Glen.[7] Another specimen is reported from Bocombe Mill Cottage Garden, near Parkham, Devon.[8]

Accessions

None known.
