OriginWageningen, The Netherlands

Ulmus 'Plantyn' (Anglicized form of 'Plantijn') was one of three Dutch hybrid elms released by the Dorschkamp Research Institute for Forestry & Landscape Planning, Wageningen, in 1973. Derived from a crossing of the Dutch hybrids '202' (U. 'Exoniensis' × U. wallichiana)[1] and '302' (U. minor '1' × U. minor '28'), it was to prove of great significance in later developments.[2][3] A selfed seedling was to become the first Dutch clone to prove effectively immune to disease, released in 1989 as 'Columella'. 'Plantyn' was also destined to be the female parent of Lutèce released in 2002.[4] In Italy, 'Plantyn' was used again as female parent in hybridizations with the Siberian Elm Ulmus pumila by the Istituto per la Protezione delle Piante (IPP), to create three new cultivars better adapted to the Mediterranean climate (see Hybrid cultivars).
