Guernsey Elm as 'Wheatleyii').[8] The Späth nursery of Berlin distributed it from c.1913 as U. campestris cornubiensis Dicksonii.[9][10] The nursery Messieurs Otin père et fils of Saint-Étienne sold an Ulmus Wheatleyi aurea pyramidalis, with leaves marbled yellow, in 1882, earlier than Dickson's introduction.[11]

Not to be confused with more common cultivars named 'Golden Elm' – 'Wredei', 'Lutescens' and 'Louis van Houtte'.

Cornish Elm in form",[8] and "conical and of dense habit".[14] The leaves are "a fine yellow colour, said to last till autumn",[1] though specimens in the north appear to colour less well (see gallery).

The horticulturalist Christopher Lloyd used 'Dickson's Golden Elm' in his herbaceous borders at Great Dixter Gardens, Northiam, East Sussex.[15] Though he gave 'Dampieri Aurea' as a synonym, photographs suggest that the cultivar planted was 'Dicksonii'.[16]

82 were planted (as Ulmus stricta Wheatleyi aurea) on the boulevard to Long Eaton district boundary before 1939 to commemorate the coronation of King George VI.[17] One example was planted at Pyrford Court, Woking, Surrey before 1985.[18]

'Dicksonii' is now very rare in the UK.

Notable trees

Among the few survivors in the UK are a tall, close-grown specimen beside Durham Cathedral (2017), and two in Peasholm Park, Scarborough, North Yorkshire, rediscovered in 1994 during a National Tree Register audit of the trees in Peasholm Glen.[19] Another specimen stands in Bocombe Mill Cottage Garden, near Parkham, Devon.[20]
