The Dieffenbachia is commonly eaten by pets and children as its fast growing nature means it’s often left in pots on the floor.

7. Peace Lily
The Peace Lily, despite its name, is not actually a member of the lily family. It’s an evergreen plant with glossy leaves and an interesting bloom that originated in South America. They’re wonderful indoor plants, good air purifiers, and quite easy to grow in many conditions, but that doesn’t make them the safest plants. In people, Peace Lily toxicity includes burning and swelling of the lips, mouth and tongue, problems with speaking or swallowing, vomiting and diarrhoea.
In animals, there are some debates as to the level of danger the plant represents. Symptoms in the past have included burning of the mouth, excessive salivation, diarrhoea, dehydration, lack of appetite and vomiting. If not treated or identified, this can lead to renal failure and death.
8. Ivy
There’s something almost magical about Ivy, sometimes called English Ivy, and the way that it slowly creeps out over the top of pots or over stone walls. In an indoor setting, Ivy is popularly hung from hanging baskets for a cascading piece of plant eye candy. Now, while Ivy has many positives, there are some things to keep an eye on. In people, Ivy can cause severe skin irritation from touching. Eating the Ivy can result in burning of the mouth and tongue, stupor, convulsions, rash and a fever. These symptoms tend only to present when quite a large amount is eaten.
In animals, pet owners should be keeping an eye out for diarrhoea, hyperactivity, gasping breaths, weakness, tremors, staggering and vomiting.
