Cultivar 'Lutescens'
Origin England

The Wych Elm cultivar Ulmus glabra 'Lutescens', commonly known as the Golden Wych Elm, arose as a sport of wych elm in York. The original tree was known as the Gallows Elm because of its proximity to the gallows in that city.[1]

Description[edit]

A medium-sized, fast-growing deciduous tree that reaches a height of approximately 15 m with a spread of about 20 m. In its first years, the tree is vase-shaped, but spreads as it matures to form a rounded canopy. The hue of the leaves varies according to light intensity. Ergo: where exposed to full sunlight the leaves are bright yellow, but in shade no more than a lime green. 'Lutescens' is arguably the best of the golden elm cultivars as it keeps its colour as it ages.

Pests and diseases[edit]

The cultivar is not known to be any less susceptible to Dutch elm disease than the species. It is highly susceptible to the elm leaf beetle Xanthogaleruca luteola [4].

Cultivation[edit]

'Lutescens' was once commonly planted in the UK, and it has been widely planted in south-eastern Australia[2] and New Zealand,[3] where it remains in cultivation as Golden Elm,[4] often being grafted on to Ulmus parvifolia rootstock.[5] In Australasia 'Lutescens' has sometimes been mistakenly sold by nurseries under the name 'Louis van Houtte'.[6] The tree was also known to have been marketed in Poland in the 19th century by the Ulrich nursery,[7] Warsaw. 'Lutescens' is not known in North America.

Notable trees[edit]

There are two notable TROBI Champion trees in England, at Pickering Park, Anlaby, measuring 16 m high by 79 cm d.b.h. in 2004, and in Dyke Road Place, Brighton, 16 m high by 76 cm d.b.h. in 2006.[8] In Australia notable specimens grow in Williamstown Botanic Gardens, Williamstown, Victoria,[9][10] in Howard Vineyard, Nairne, South Australia,[11][12] and at 'Poacher's Pantry', Hall, Canberra,[13] and there is a mature tree in the Royal Tasmanian Botanical Gardens, Hobart.[14][15] Four trees stand in Cathedral Square, Christchurch, New Zealand.[16]
