Origin Netherlands

Ulmus 'Stavast' is a hybrid elm cultivar raised at Wageningen in the Netherlands as clone '622' from the crossing of 'Commelin' with clone '202', itself a hybrid of the Exeter Elm Ulmus 'Exoniensis' and the Himalayan Elm Ulmus wallichiana.

Description[edit]

The tree is distinguished solely by its dense root system.

Pests and diseases[edit]

'Stavast' has only a moderate resistance to Dutch elm disease, rated 3 out of 5.[1]

Cultivation[edit]

'Stavast' has never been in commerce in its own right but retained as a rootstock for grafting, as its dense root system quickly stabilized young trees.[2] A number of 'Stavast' trees were exported to New Zealand for use in trials at the Hortresearch station at Palmerston North in the 1990s.

Etymology[edit]

The name 'Stavast' is Dutch for "stand firmly", but is also used to describe someone of resolute character.

Notable trees[edit]

Examples can be found on the elm trial plantation at "Lepelaarweg", Zeewolde. In 2009 one example was planted in "Het Egeltjesbos" a public park in the village De Kwakel, Uithoorn City Council, The Netherlands.[citation needed]
