| Origin |
| The Netherlands |
The hybrid cultivar Den Haag is a Dutch development derived from a crossing of the Siberian Elm U. pumila and U. × hollandica Belgica by S. G. A. Doorenbos in 1936. The tree is of modest proportions, achieving a maximum height of 6m, and is distinguished by its foliage, creamy-white on emergence, 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.
