Also known as: Dracaena fragrans, Cornstalk Dracaena, Happy Plant · Dracaena fragrans

What makes it toxic

Steroidal saponins in foliage and stems, which irritate and inflame the lining of the stomach and intestines.

Warning signs to watch for

Drooling, vomiting (frequently with blood), diarrhea, lethargy and loss of appetite within hours to a day.

What to do if your dog eats it

Remove access and call your vet, particularly for blood-tinged vomit or a dog that will not eat. Supportive care usually resolves cases within a couple of days.

Common questions

Why does the vomit sometimes contain blood?

Saponins are strong GI irritants and can erode the stomach lining enough to produce small bleeds. Bloody vomit is the signal to stop monitoring and call the vet.

Are Dracaena marginata and lucky bamboo equally toxic?

Yes. The Dracaena genus shares these saponins, so dragon tree, corn plant and lucky bamboo all require the same precautions.
