Bird of Paradise. Who would have thought this flower with a very beautiful English name could be dangerous. Especially if you have a pet, be careful. Don't let your pet eat this one flower. Especially dogs.
If that happens, it is likely that your pet, especially dogs, will experience diarrhea, burning tongue, vomiting or very much saliva.
This poison from Bird of Paradise contains hydrocyanic acid which can cause poison in some plants. If consumed continuously it will be a deadly poison for pets.
