A single tree can shed hundreds of thousands of seeds a year and send up root suckers dozens of feet away, forming thickets that crowd out natives, crack pavement and foundations, and poison nearby plants with its own chemicals. It is also the favored host of the spotted lanternfly. Do not plant it.","care":"Not recommended for planting anywhere in the US. To remove it, cutting alone triggers massive root suckering; the effective approach is a basal-bark or cut-stump herbicide treatment in mid to late summer, followed by several years of pulling or treating sprouts. Report it to your state invasive species program if it appears in a natural area.","benefits":["fast_canopy","drought_tolerant"],"uses":[],"cautions":["invasive_elsewhere","weak_wood","large_roots","surface_roots","allergenic_pollen"],"image_url":"https://upload.wikimedia.org/wikipedia/commons/e/eb/G%C3%B6tterbaum_%28Ailanthus_altissima%29.jpg","image_credit":"Darkone (talk · contribs), CC BY-SA 2.5, via Wikimedia Commons","sources":["https://plants.usda.gov/plant-profile/AIAL","https://www.texasinvasives.org/plant_database/detail.php?symbol=AIAL","https://plants.ces.ncsu.edu/plants/ailanthus-altissima/","https://www.fs.usda.gov/database/feis/plants/tree/ailalt/all.html"],"data_note":null,"updated_at":"2026-11-08T01:00:46.205Z","page_url":"https://treerm.org/trees/ailanthus-altissima","markdown_url":"https://treerm.org/trees/ailanthus-altissima.md","regions":[{"country":"CN","region":null,"locality":null,"status":"native","note":"Native to China","source_url":null},{"country":"US","region":null,"locality":null,"status":"invasive","note":"USDA PLANTS: introduced in the lower 48 states, Hawaii and Canada; Texas Invasives reports it present in 41 states","source_url":"https://plants.usda.gov/plant-profile/AIAL"},{"country":"US","region":"NC","locality":null,"status":"invasive","note":"Listed as invasive by the NC Invasive Plant Council (per NC State Extension Plant Toolbox)","source_url":"https://plants.ces.ncsu.edu/plants/ailanthus-altissima/"},{"country":"US","region":"TX","locality":null,"status":"invasive","note":"Listed in the Texas Invasives (texasinvasives.org) plant database.
