OriginCanada

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.[1][2] 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.[3]

Description

Similar in appearance to 'Jacan'.[1] The species does not sucker from roots.[4]

Pests and diseases

The tree is more resistant to Dutch elm disease than 'Jacan', and is also resistant to elm leaf beetle Xanthogaleruca luteola [1].[1]

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.[5] A grove of 'Mitsui Centennial' was planted in 1980 near the Parsee Fountain on Broadwalk, Regents Park, London.[6][7]
