Tulips
It may come as a surprise to find that tulips are poisonous, even though they probably thrive around your backyard. They’re especially poisonous to pets, like horses, cats, and dogs. If they ingest the tulip bulb, they’ll experience diarrhea, hypersalivation, depression, and vomiting. If a human ingests a tulip bulb, they’ll experience mouth and skin irritation, dizziness, and abdominal upset. People who handle tulips for work or pleasure may experience “tulip fingers.” This is an irritating rash caused by a rash called tuliposide (Poison Control).
