Ulmus 'Sapporo Autumn Gold'

Ulmus 'Sapporo Autumn Gold' is one of the most commercially successful hybrid elm cultivars ever marketed, widely planted across North America and western Europe, although it has now been largely supplanted by more recent introductions.

In trials in France by Cemagref at Nogent-sur-Vernisson, Loiret, it was found to grow too vigorously in hedgerow conditions, eclipsing neighbouring shrubs and consequently creating gaps.

In the UK, 'Sapporo Autumn Gold' has been found to host the endangered white-letter hairstreak butterfly (Satyrium w-album), whose larvae feed exclusively on elm.

[17] The very first tree planted in the UK in 1979 at the Pitney Bowes technology company by Denis Thatcher (where he was a director), survived in perfect health as of 2012;[18] however Poundland now occupy the site and the land was flattened in 2013/2014.

The largest specimen in Europe known to Dutch elm expert Hans M. Heybroek grows at the Istituto per la Protezione delle Piante's Monna Giovanella nursery at Antella, near Florence (see Infobox photo), but this too was badly damaged by a storm in 2020.
