Are Blue Holly Poisonous to Children?

Children who encounter the berries of a blue holly may be attracted at first, but they will likely spit the fruit out quickly. The blue holly berry tastes awful to humans. If blue holly sprigs are typically brought into your home for the holidays, consider removing the berries first. This will reduce the chances of them falling off and becoming an easy target for curious kids.

Still, keep watch for symptoms like diarrhea, lethargy, and vomiting as these are signs that your dog has consumed a large quantity. Seek veterinary help if you think your dog has been poisoned by blue holly.
