The Cathedral variety is an interspecific hybrid of Ulmus japonica and Ulmus pumila. The tree reaches a height of 15–20 meters with a comparable crown width. It has alternate oblong-ovate leaves with double-serrated margins, which are green in summer and turn yellow or orange in autumn.
The plant possesses high resistance to Dutch elm disease and Verticillium wilt, as well as resistance to the elm leaf miner. The variety tolerates air pollution and soil salinity well, preferring sunny locations with fertile, well-drained soil. Due to branching characteristics at a young age, the tree may require formative pruning.
