Celtis edulis seems to be poorly represented in cultivation in our area. At Kew, a seedling from the Beyer, Erskine and Cowley Expedition to Korea (BECX 275) in 1982 is a rather sparse small tree of 2.5 m. The collection was made at 816 m in Chungcheongnam-do Province, South Korea. Another small tree, at the JC Raulston Arboretum, received in 1996, is now 2.3 m and looking good, with grass-green leaves that are neatly toothed and have a distinctive elongated tip.
