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'
