The mutant-elm cultivars are usually grafted, the "weeping" elms 'Camperdown' and 'Horizontalis' at 2–3 m (7–10 ft), the dwarf cultivars 'Nana' and 'Jacqueline Hillier' at ground level. Since the Siberian elm is drought tolerant, in dry countries, new varieties of elm are often root-grafted onto this species. [16]
