Description

The tree is fastigiate when young, but like its parent 'Dampieri' can become more spreading with age.^[3] It has broad, crinkled leaves clustered on short shoots; when these are young they are suffused yellow, but as the tree ages they revert to green.

Pests and diseases

'Wredei' is susceptible to Dutch elm disease.

Cultivation

Commonly known as the Golden Elm, 'Wredei' is currently one of the most popular elms on sale in Europe owing to its colourful foliage and modest size, making it suitable for the smaller garden.
