It resists Dutch elm disease and elm leaf beetle, tolerates heat, drought, wind and poor soil, and is planted as an elm substitute on streets in New York, Philadelphia and many western cities. 'Green Vase', 'Village Green', 'City Sprite' and the low 'Wireless' cover sites from wide boulevards to under power lines.","care":"Plant in full sun in well-drained soil and water regularly for the first two years. Prune in the dormant season to remove narrow crotches with included bark, which can split in storms. Japanese beetles and leafrollers chew foliage; otherwise it is nearly disease-free, though cold snaps can kill twigs in zone 5.","benefits":["shade","fall_color","drought_tolerant","storm_resistant","fast_canopy"],"uses":["street_tree","yard_shade","parks","small_yard"],"cautions":["none"],"image_url":"https://upload.wikimedia.org/wikipedia/commons/8/87/Zelkova_serrata_Noma_keyaki01.jpg","image_credit":"ja:User:Miya, CC BY-SA 4.0, via Wikimedia Commons","sources":["https://plants.ces.ncsu.edu/plants/zelkova-serrata/","https://plants.usda.gov/plant-profile/ZESE","https://en.wikipedia.org/wiki/Zelkova_serrata"],"data_note":null,"updated_at":"2026-11-08T01:00:46.205Z","page_url":"https://treerm.org/trees/zelkova-serrata","markdown_url":"https://treerm.org/trees/zelkova-serrata.md","regions":[{"country":"JP","region":null,"locality":null,"status":"native","note":"Native to Japan, Korea, eastern China and Taiwan.","source_url":"https://en.wikipedia.org/wiki/Zelkova_serrata"},{"country":"AU","region":"NSW","locality":"Sydney","status":"recommended","note":"On the City of Sydney Street Tree Master Plan 2023 precinct planting palette","source_url":"https://www.cityofsydney.nsw.gov.au/-/media/corporate/files/publications/strategies-action-plans/street-tree-master-plan/precinct-summaries-2023.pdf"},{"country":"US","region":"CA","locality":"Sacramento","status":"recommended","note":"On the Sacramento Tree Foundation Shady 80 recommended trees list","source_url":"https://sactree.org/best-trees-for-sacramento/"},{"country":"US","region":"CA","locality":"San Jose","status":"recommended","note":"On the Our City Forest Community Nursery tree species list","source_url":"https://www.ourcityforest.org/nursery-species"},{"country":"US","region":"CO","locality":"Denver","status":"recommended","note":"On the Denver Office of the City Forester Approved Street Tree List","source_url":"https://www.denvergov.org/content/dam/denvergov/Portals/747/documents/forestry/Street_tree_guide.pdf"},{"country":"US","region":"MA","locality":"Boston","status":"recommended","note":"On the City of Boston Urban Forestry Division recommended public street trees list","source_url":"https://www.boston.gov/urban-forestry-division"},{"country":"US","region":"NY","locality":"New York","status":"recommended","note":"On the NYC Parks Street Tree Planting Approved Species List","source_url":"https://www.nycgovparks.org/trees/street-tree-planting/species-list"},{"country":"US","region":"OR","locality":"Portland","status":"recommended","note":"'Green Vase' zelkova is on Portland's list for planting strips 8.5 ft and wider.","source_url":"https://www.portland.gov/trees/85-foot-wide-and-greater-planting-spaces-without-high-voltage-power-lines"},{"country":"CA","region":null,"locality":null,"status":"adapted","note":"Planted in milder parts of southern Ontario and coastal British Columbia.","source_url":"https://en.wikipedia.org/wiki/Zelkova_serrata"},{"country":"US","region":null,"locality":null,"status":"adapted","note":"Introduced; widely planted as a street tree in zones 5 to 8.","source_url":"https://plants.ces.ncsu.edu/plants/zelkova-serrata/"}],"license":"CC-BY-4.0"}
