Ulmus 'Hillieri'
Elm cultivar
The elm cultivar Ulmus 'Hillieri' arose from a chance seedling at Hillier's Pitt Corner nursery near Winchester, England, in 1918,[1] and was marketed from 1928 as Ulmus hillieri,[2] a name accepted by Christine Buisman in her 1931 labelling of a specimen in France. Since at least 1944 the tree has been determined a form of Ulmus × hollandica, its designation at Kew Gardens, in Green,[3] and in later Hillier catalogues.[4] In 1940, 'Hillieri' was noted as being a hybrid of uncertain origin.[5] Krüssmann notes that for a time the tree was listed by Hilliers as U. × hillieri.[6]
Not to be confused with Ulmus 'Jacqueline Hillier', which also has a shrubby habit but much smaller leaves.
