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] The tree was named to mark the centenary in 1980 of Mitsui & Co. and was one of three Japanese elm cultivars sourced from Canada (the others 'Jacan' and 'Thomson') donated to the UK in that year by the company's London office.[3]
