How complete this information is
The safety information on this page is partial. Where a source covers a point, it is shown; where none does, the page says so.

Toxic to pets
No ASPCA entry found.

No source we checked assesses this plant for pets, so the app makes no pet claim either way.

Look-alike warning
Could be mistaken for Plants that share its name. To tell them apart: Sweet chestnut is not horse chestnut (Aesculus, toxic)..
