| WARF, Wisconsin, USA |
The elm hybrid Cathedral is one of several clones derived from crossings of the Siberian Elm U. pumila with the Japanese Elm U. davidiana var. japonica at the University of Wisconsin. Patented in 1994, it is distinguished from its siblings Sapporo Autumn Gold and New Horizon by its large, elliptical leaves, < 14 cm long by < 8 cm broad, almost the same size and shape of those of its male parent, the Japanese Elm, spinach green when mature, turning yellow and orange in autumn. It is, however, somewhat less resistant to Dutch elm disease than its siblings, although damage is usually confined to the branch tips.
