Ulmus davidiana var. japonica 'Mitsui Centennial'

The Japanese Elm cultivar Ulmus davidiana var. japonica 'Mitsui Centennial' is a cold-resistant selection raised at the Morden Experimental Station, Manitoba, Canada, in the 1970s, originally for use in the prairie regions. It was named to mark the centenary in 1980 of the London branch of Mitsui & Co., being one of a batch of Asiatic elms, some sourced from Canada (including 'Jacan'), donated to the UK in that year by the company.

Description
Similar in appearance to 'Jacan'. The species does not sucker from roots.

Pests and diseases
The tree is more resistant to Dutch elm disease than 'Jacan', and is also resistant to elm leaf beetle Xanthogaleruca luteola.

Cultivation
Largely restricted to Canada, 'Mitsui Centennial' is represented in Europe by a specimen at the Sir Harold Hillier Gardens in Hampshire, England, where it has grown strongly in a sheltered location on London Clay. A grove of 'Mitsui Centennial' was planted in 1980 near the Parsee Fountain on Broadwalk, Regents Park, London.
