OriginGermany

The hybrid elm cultivar Ulmus × hollandica 'Wredei', also known as Ulmus × hollandica 'Dampieri Aurea' and sometimes marketed as Golden Elm, originated as a sport of the cultivar 'Dampieri' at the Alt-Geltow Arboretum, near Potsdam, Germany, in 1875.[1][2]

Not to be confused with two other popular cultivars named 'Golden Elm', Ulmus glabra 'Lutescens' and Ulmus 'Louis van Houtte'.

Description[edit]

The tree is fastigiate when young,[3] but like its parent 'Dampieri' can become more spreading with age.[4] It has broad, crinkled leaves clustered on short shoots; when these are young they are suffused yellow, but as the tree ages they revert to green.

Pests and diseases[edit]

'Wredei' is susceptible to Dutch elm disease.

Cultivation[edit]

'Wredei' was distributed by the Louis van Houtte and Späth nurseries in the late 19th century (Louis van Houtte described it in 1881 as a "superbe nouveauté").[5][6] Späth supplied one tree, as U. montana fastigiata aurea, to the Dominion Arboretum, Ottawa, in 1893,[7] and three in 1902 to the Royal Botanic Garden Edinburgh in 1902 as U. montana fastigiata Dampieri Wredei.[8] 'Dampieri Aurea' appears in the 1902 catalogue of the Bobbink and Atkins nursery, Rutherford, New Jersey,[9] and in Kelsey's 1904 catalogue, New York.[10] Ulmus Wredei aurea was introduced to Australia in the early 20th century.[11] 'Wredei' is currently one of the most popular elms on sale in Europe owing to its colourful foliage and modest size.

For the 'Golden Elm' at Great Dixter Gardens, Northiam, East Sussex,[12] apparently miscalled 'Dampieri Aurea' by the horticulturalist Christopher Lloyd,[13] see U. minor 'Dicksonii'.

Notable trees[edit]

In the UK, the Tree Register of the British Isles (TROBI) Champion is at Blakers Park, Brighton, measuring 17 m high and 57 cm d.b.h. in 2009, when the leaf colour was reverting to green.[14]

Etymology[edit]

The tree is named for Joseph Wrede (1831–1912), Royal Horticultural Inspector at the Royal State Nursery, Alt-Geltow, Potsdam, and curator of the Alt-Geltow Arboretum.[15]
