|---|---|
| Genus | Ulmus |
| Hybrid parentage | 'Commelin' × '202' (U. 'Exoniensis' × U. wallichiana) |
| Cultivar | 'Stavast' |
| Origin | Netherlands |
Ulmus 'Stavast' is a Dutch hybrid elm cultivar raised at the Dorschkamp Research Institute for Forestry & Landscape Planning, Wageningen, as clone '622' from the crossing of 'Commelin' with clone '202', itself a hybrid of the Exeter Elm Ulmus 'Exoniensis' and Himalayan Elm Ulmus wallichiana.
Description
[edit]The tree is distinguished 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 not been in commerce in its own right much. It is retained as a rootstock for grafting, as its dense root system quickly stabilized young trees.[2] It was used as a rootstock for grafting related elms like ‘Dodoens’, ‘Clusius’ and ‘Plantijn’, cultivars now propagated by rooted cuttings.
Nevertheless, specimens were planted in the Netherlands: in the elm trial plantation at "Lepelaarweg", Zeewolde, and 1 tree in "Het Egeltjesbos" public park in village De Kwakel, Uithoorn.[citation needed] In 2018, at Wijdemeren city council ‘s-Gravelandsevaartweg, Loosdrecht, planted 10. [citation needed] Wijdemeren holds the Netherlands Plant Collection Elm since 2020. Information given by Wijdemeren tree officer M. Tijdgat, also Elm collection holder.
A number of 'Stavast' trees were exported to New Zealand for use in trials at the Hortresearch station at Palmerston North in the 1990s.[citation needed]
Etymology
[edit]The name 'Stavast' is Dutch for "stand firmly", but is also used to describe someone of resolute character.
