Cathedral Elm Ulmus x 'Cathedral'
- Phonetic Spelling
- ULM-us
- Description
-
Cathedral Elm is a hybrid developed at the University of Wisconsin by crossing Japanese Elm (Ulmus parvifolia) with Siberian Elm (Ulmus pumila). It has a spreading vase-like shape, with good resistance to Dutch elm disease, elm leaf beetle and other leaf-cutting insects. It requires regular pruning during the first 15 years to develop a sound structure.
Cathedral Elm is tolerant of various soil types, pH ranges, pollution and salt. The dense canopy and upright spreading habit make it good for use as a shade or street tree.
