Houseplants toxic to children: the list every parent should know
Houseplants make a home feel alive, but some of the most popular ones are irritating — even toxic — if a young child puts them in their mouth. At the age when everything gets tasted, it pays to know which ones to watch and which to keep out of reach. Here is the list of the most common species, the symptoms to recognize, and the right reflexes.

Between 6 months and 5 years, exploration happens through the mouth: torn leaves, soil, berries — anything can be tasted. Many very common houseplants defend themselves chemically. The good news: in the vast majority of cases, ingestion is limited to unpleasant but harmless irritation, precisely because the pain is immediate and stops the child from continuing. The real concern is bulbs and a few more potent species.
The most common toxic houseplants
The family most often involved at home is the Araceae. Their leaves contain calcium oxalate crystals that, when chewed, release an immediate burning sensation and swelling of the mouth and throat.
| Plant | Substance | Effect if ingested |
|---|---|---|
| Dumb cane (Dieffenbachia) | Calcium oxalates | Intense pain, drooling, mouth swelling |
| Philodendron | Calcium oxalates | Mouth irritation, difficulty swallowing |
| Pothos (Epipremnum) | Calcium oxalates | Burning lips and tongue |
| Peace lily (Spathiphyllum) | Calcium oxalates | Irritation, drooling |
| Monstera, Alocasia, Caladium | Calcium oxalates | Mouth pain, swelling |
| Amaryllis (bulb especially) | Alkaloids (lycorine) | Nausea, vomiting, stomach pain |
| Ficus | Latex (sap) | Mouth and skin irritation |
| Poinsettia & euphorbias | Irritant latex | Mouth and skin irritation (often overstated) |
| Snake plant (Sansevieria) | Saponins | Nausea, vomiting (mild toxicity) |
This covers the most frequent cases, not every species. For a specific plant, the safest move is to identify it: our toxic plants guide by genus details toxicity species by species, with humans, cats and dogs listed separately.
Symptoms of ingestion
With the Araceae (the most common), signs appear within minutes:
- Pain or burning in the mouth, on the lips and tongue;
- Heavy drooling, refusing to eat or drink;
- Swelling of the lips, tongue or throat;
- Sometimes nausea or vomiting;
- On skin contact with the sap: redness or itching of the skin and eyes.
Bulbs (amaryllis) and some species tend to cause digestive upset instead. Significant throat swelling or breathing difficulty, though rare, calls for immediate emergency help.
- Remove any remaining pieces from the mouth and rinse with water;
- Offer a little water to soothe the irritation;
- Do not induce vomiting and do not give milk without medical advice;
- Call Poison Control or emergency services;
- Keep a piece of the plant to help identify it.
How to childproof your home without giving up plants
You don't have to get rid of all your plants. A few habits are enough:
- Height first: high shelves, hanging planters, tops of furniture — out of reach of hands and mouths.
- Bulbs away: store amaryllis and forced bulbs where children can't reach.
- Mind fallen leaves: pick up a dropped leaf or flower right away.
- Learn to recognize them: knowing exactly which plants you own changes everything. Photograph them once and for all.
Photograph every plant in your home with Leafy. The app identifies the species and shows its toxicity for humans and for pets separately, with sources to back it up. You'll know at a glance which ones to move up high — no guessing.
Safe plants for homes with children
Good news: many beautiful plants are safe on contact or occasional chewing. Calathea, most ferns, spider plant (Chlorophytum), pilea and peperomia are excellent choices. We cover the best options in our guide to non-toxic plants (handy if you have a cat too). And if you're just starting out, begin with easy-care plants.

Frequently asked questions
Which houseplants are most toxic to children? Mainly the Araceae (dieffenbachia, philodendron, pothos, peace lily, monstera, alocasia) because of calcium oxalates, plus amaryllis, ficus and euphorbias.
Is poinsettia really dangerous? Its danger is greatly overstated: it mostly causes mouth and skin irritation, rarely anything serious. Keep it out of reach as a precaution, without panic.
What if my child chewed a plant? Remove the pieces, rinse the mouth, do not induce vomiting, and call Poison Control while keeping a sample of the plant.
How do I know if a specific plant is dangerous? Identify it with Leafy: toxicity for humans and pets is shown separately, with sources. Developers can integrate this data via the Leafy API.
