'Cathedral' (elm hybrid)
Encyclopedia : C : CA : CAT : 'Cathedral' (elm hybrid)
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 in the USA. It is distinguished from its siblings Sapporo Autumn Gold and New Horizon by its large leaves, almost the same size and shape of those of its male parent, Japanese Elm. It is, however, somewhat less resistant to Dutch elm disease than its siblings.
It is not known to be commercially available in Europe.
