Origin
The Netherlands

The hybrid cultivar elm 'Den Haag' is a Dutch development derived from a crossing of the Siberian Elm Ulmus pumila and Ulmus × hollandica 'Belgica' in 1936 by S. G. A. Doorenbos (1891-1980), Director of Public Parks in The Hague. The tree is distinguished by its pendent branches, and foliage, creamy-white on emergence, but turning lime-green and ultimately deep green by midsummer. Although reputed to be moderately resistant to Dutch elm disease, drought, and frost, the tree has brittle branches, and is vulnerable to Coral-spot Fungus Nectria cinnabarina [1] [2].

The specimen shown grows at Southsea Common, Portsmouth, England, one of only two known in the UK.

'Den Haag' is not known to have been introduced to North America, but has been planted in New Zealand.
