'Arno' is a cultivar derived from a crossing of the Dutch hybrid cultivar 'Plantyn' with the Siberian Elm Ulmus pumila clone S.2. It was raised by the Istituto per la Protezione delle Piante (IPP) in Florence, and released for sale in 2007. 'Arno' is of erect habit with upward main branches forming an oval to round crown. The tree is remarkably fast-growing, though not as quick as its contemporary 'Fiorente'. The trunk is straight, and branches at a height of 3 m; the bark is grey-green, with grey-orange fissures. The alternate deciduous leaves are of moderate size, < 9 cm long by < 5 cm wide, ovate to lanceolate, featuring yellowish - green undulate margins; they remain green throughout autumn and are usually shed relatively late. 'Arno' is highly resistant to Dutch Elm Disease, and has reputedly performed extremely well in trials in northern Italy, even where grown on poor clay soils [1]. The clone was introduced to the UK by Butterfly Conservation in 2007.
