About: Ulmus 'Cathedral'

Ulmus 'Cathedral' is a hybrid cultivar raised at University of Wisconsin–Madison (no. W44-25) patented in 1994. Arising from a chance crossing of the Japanese elm (female parent) and Siberian elm, seed was sent in 1958 by Prof. Nobuku Takahashi and his colleagues at the Sapporo Botanical Garden of Hokkaido University, Sapporo, to Eugene Smalley at Wisconsin–Madison; 'Cathedral' is thus a sibling of 'Sapporo Autumn Gold'.
