Cultivation
One specimen which grew at the Strona Arboretum, University of Life Sciences, Warsaw, Poland, (as ''Ulmus celtidea'' Litv.) died circa 2006. The tree was grown from seed collected from a tree at the Arboretum of the Forest-Technical Academy in St. Petersburg in 1961; it is not known whether this source is still alive. No cultivars or hybrid cultivars are known.
