The rough leaves turn plain yellow in fall and small sweet purple berries hang on through winter for birds. It shrugs off drought, flooding, wind, salt and pollution, is immune to Dutch elm disease, and is one of the toughest shade trees for streets and parking lots; the wood is soft and ice can break limbs.","care":"Easy to transplant into almost any soil in full sun. Water for the first season, then little is needed. Prune when dormant. Nipple galls and witches' broom are common but cosmetic; woolly aphids can drip honeydew.","benefits":["shade","fast_canopy","drought_tolerant","flood_tolerant","salt_tolerant","wildlife","birds","pollinators","edible","long_lived"],"uses":["street_tree","yard_shade","parks","windbreak"],"cautions":["weak_wood","messy_fruit"],"image_url":"https://upload.wikimedia.org/wikipedia/commons/8/82/Celtis_occidentalis_20090606.jpg","image_credit":"Chhe (talk), Public domain, via Wikimedia Commons","sources":["https://plants.ces.ncsu.edu/plants/celtis-occidentalis/","https://mortonarb.org/plant-and-protect/trees-and-plants/hackberry/","https://plants.usda.gov/plant-profile/CEOC","https://en.wikipedia.org/wiki/Celtis_occidentalis"],"data_note":null,"updated_at":"2026-11-08T01:00:46.205Z","page_url":"https://treerm.org/trees/celtis-occidentalis","markdown_url":"https://treerm.org/trees/celtis-occidentalis.md","regions":[{"country":"CA","region":null,"locality":null,"status":"native","note":"Native to southern Ontario, Quebec and a pocket in Manitoba.","source_url":"https://plants.usda.gov/plant-profile/CEOC"},{"country":"US","region":null,"locality":null,"status":"native","note":"Native across the Midwest and eastern US from the Dakotas and Oklahoma to New England and North Carolina (more than 15 states).","source_url":"https://plants.usda.gov/plant-profile/CEOC"},{"country":"CA","region":"ON","locality":"Toronto","status":"recommended","note":"On Toronto's list of species planted on streets (native to Ontario).","source_url":"https://www.toronto.ca/services-payments/water-environment/trees/tree-planting/species-planted-on-streets/"},{"country":"US","region":"CA","locality":"Los Angeles","status":"recommended","note":"On the City Plants (Los Angeles) Street Tree Species List","source_url":"https://www.cityplants.org/street-tree-species-list/"},{"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":"OR","locality":"Portland","status":"recommended","note":"On Portland's approved list for 6.0 to 8.4 ft planting strips without high-voltage lines.","source_url":"https://www.portland.gov/trees/60-84-foot-wide-planting-spaces-without-high-voltage-power-lines"},{"country":"US","region":"WA","locality":"Seattle","status":"recommended","note":"Offered as a street tree (8 ft+ planting strip) in Seattle's Trees for Neighborhoods 2026 program.","source_url":"https://www.seattle.gov/trees/2026-tree-options"}],"license":"CC-BY-4.0"}
