It leafs out late and drops early. Female trees carry leathery brown pods all winter; podless male cultivars ('Espresso', 'Prairie Titan') avoid the litter. It tolerates heat, drought, salt, pollution and ice, making it one of the most dependable city trees.","care":"Plant small, since the taproot makes large trees hard to move, in full sun and any reasonable soil. Water the first two seasons, then it needs little. Prune when dormant for structure. It has no serious pests or diseases; leaves, seeds and pod pulp are toxic to people and pets.","benefits":["shade","drought_tolerant","salt_tolerant","flood_tolerant","storm_resistant","fall_color","flowers","nitrogen_fixing"],"uses":["street_tree","yard_shade","parks"],"cautions":["toxic_parts","heavy_litter","large_roots"],"image_url":"https://upload.wikimedia.org/wikipedia/commons/f/f4/Gymnocladus_dioicus_JPG1a.jpg","image_credit":"Jean-Pol GRANDMONT, CC BY 3.0, via Wikimedia Commons","sources":["https://plants.ces.ncsu.edu/plants/gymnocladus-dioicus/","https://mortonarb.org/plant-and-protect/trees-and-plants/kentucky-coffeetree/","https://plants.usda.gov/plant-profile/GYDI","https://en.wikipedia.org/wiki/Gymnocladus_dioicus"],"data_note":null,"updated_at":"2026-11-08T01:00:46.205Z","page_url":"https://treerm.org/trees/gymnocladus-dioicus","markdown_url":"https://treerm.org/trees/gymnocladus-dioicus.md","regions":[{"country":"CA","region":"ON","locality":null,"status":"native","note":"Native to southern Ontario.","source_url":"https://plants.usda.gov/plant-profile/GYDI"},{"country":"US","region":null,"locality":null,"status":"native","note":"Native from Kentucky and Connecticut west to Kansas, Nebraska and South Dakota, north to Wisconsin and Michigan, south to Louisiana (more than 15 states).","source_url":"https://plants.usda.gov/plant-profile/GYDI"},{"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":"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":"DC","locality":"Washington","status":"recommended","note":"On the Casey Trees Tree Rebate eligible species list","source_url":"https://caseytrees.org/rebate"},{"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":"On Portland's approved street tree 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":"US","region":"TX","locality":"Dallas","status":"recommended","note":"On the City of Dallas Article X Approved Tree List","source_url":"https://dallas.gov/departments/sustainabledevelopment/buildinginspection/DCH%20documents/pdf/BI_Approved%20Tree%20List.pdf"}],"license":"CC-BY-4.0"}
