Cone-like seed clusters persist through winter. It is a magnificent lawn or park tree but too large and brittle for small lots or narrow planting strips, and its fleshy roots and leaves scorch in drought.","care":"Plant in early spring in deep, moist, well-drained soil and keep it evenly watered; it drops leaves in hot, dry spells. Structural pruning when young helps because limbs break in wind and ice. Aphids and the sooty mold that grows on their honeydew are the usual complaint; verticillium wilt and cankers are occasional.","benefits":["shade","fast_canopy","flowers","fall_color","pollinators","wildlife","birds","long_lived"],"uses":["yard_shade","parks","timber"],"cautions":["weak_wood","surface_roots","heavy_litter","pest_prone"],"image_url":"https://upload.wikimedia.org/wikipedia/commons/3/37/Liriodendron_tulipifera_%28arbre%29_-_Laeken.JPG","image_credit":"Jean-Pol GRANDMONT, CC BY 3.0, via Wikimedia Commons","sources":["https://plants.ces.ncsu.edu/plants/liriodendron-tulipifera/","https://mortonarb.org/plant-and-protect/trees-and-plants/tuliptree/","https://plants.usda.gov/plant-profile/LITU","https://en.wikipedia.org/wiki/Liriodendron_tulipifera"],"data_note":null,"updated_at":"2026-11-08T01:00:46.205Z","page_url":"https://treerm.org/trees/liriodendron-tulipifera","markdown_url":"https://treerm.org/trees/liriodendron-tulipifera.md","regions":[{"country":"CA","region":"ON","locality":null,"status":"native","note":"Native to the Carolinian zone of southern Ontario.","source_url":"https://plants.usda.gov/plant-profile/LITU"},{"country":"US","region":null,"locality":null,"status":"native","note":"Native across the eastern US from Connecticut and Illinois to Florida and Louisiana (more than 15 states); state tree of Indiana, Kentucky and Tennessee.","source_url":"https://plants.usda.gov/plant-profile/LITU"},{"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":"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":"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":"GA","locality":"Atlanta","status":"recommended","note":"On the Trees Atlanta Top 50 Atlanta Trees list","source_url":"https://treesatlanta.org/resources/50-atlanta-trees/"},{"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"}],"license":"CC-BY-4.0"}
