Ulmus x hollandica
Ulmus x hollandica, commonly called Dutch Elm is a natural hybrid (hence the ‘x’ in the scientific name) between Wych Elm Ulmus glabra and Field Elm Ulmus minor, which occurs commonly across Europe where the parent species overlap. There have been around 40 cultivars arising from the species.
Funky Fact File: The ‘Great Elm’ in the grove at Magdalen College, Oxford was the largest elm known in Britain before being blown down (1911). Fortunately it had been photographed a decade earlier. The fallen tree comprised 81 cubic meters of timber making it the largest tree of any kind in this country. Paintings by Constable including The Cornfield, feature mature Dutch elms.
