Pet & Human Safety
People: Not researchedPets: Not on the ASPCA lists as we read them
Neither ASPCA nor NC State Extension lists a toxicity verdict for Bougainvillea. It commonly appears on informal "pet-safe" plant lists online, but that claim is not confirmed by ASPCA or a land-grant university source, so it is recorded here as unconfirmed rather than non-toxic. The real, well-documented hazard is mechanical: sharp, curved thorns that can injure a curious pet or child.
