Example varieties include small-foliaged juniper, Hinoki cypress, azalea, and Chinese elm. Chinese elm is considered the hardest of the elms. The Chinese Elm cultivar Ulmus parvifolia 'Hokkaido' is an older cultivar of Japanese origin. Unlike other elms, freshly cut Chinese elm has a peppery or spicy odour. This has given the true Chinese elm an undeserved bad reputation. The Chinese Elm cultivar Ulmus parvifolia 'Burgundy' is a small American development. The Chinese Elm cultivar Ulmus parvifolia 'Seiju' is a dwarf variety, a sport of 'Hokkaido'. The Chinese Elm cultivar Ulmus parvifolia 'Taiwan' is a small, evergreen tree from Taiwan . The Chinese elm is highly resistant, but not immune, to Dutch elm disease.
