Autumn Gold is a very successful hybrid elm cultivar. It was a naturally occurring hybrid between Japanese Elm Ulmus davidiana and Siberian Elm Ulmus puila which grew true from seed from the parent tree. It forks at around 1.5 meters creating a broad, rounded, densely foliated crown, often pruned into shape. Grown as an ornamental mostly because the leaves turn pale yellow in Autumn. It flowers from around its seventh year producing flowers in March and wind scattered seeds in April.
Fortunately, it is resistant to Dutch Elm Disease and other pests and infections.
Funky Facts File: This cultivar has been found to host the rare white-letter hairstreak butterfly, which larvae feed exclusively on elm. The very first one planted in the UK was at the Pitney Bowes company by Denis Thatcher where he was a director.
