Seiju Elm bonsai
Species	Ulmus parvifolia
Cultivar	'Seiju'
Origin	US

The Chinese Elm cultivar Ulmus parvifolia 'Seiju' is a dwarf variety, a sport of 'Hokkaido'.^[1]

'Seiju' is described as smaller than Catlin and faster growing than Hokkaido, distinguished from the latter by its larger leaves.^[2]

The species and its cultivars are highly resistant, but not immune, to Dutch elm disease, and unaffected by the Elm Leaf Beetle Xanthogaleruca luteola.^[3]

The tree is commercially available in the United States and Australia where it is popular as a bonsai subject.^[4] The tree was also listed in the UK until 2002.
