Poisonous Houseplants for Babies: Which Common Plants to Remove Now

The houseplant on your windowsill probably came from a garden center with a cheerful little care tag. Watering schedule, light requirements, maybe a common name. What those tags almost never include: whether your baby can survive chewing on a leaf.

Most parents think about outlet covers and cabinet locks. Far fewer think about the pothos trailing over the bookshelf or the peace lily on the kitchen counter. But poison control centers field calls about plant exposures every day, and the children involved are almost always under five, almost always curious, and almost always fast.

About 3 million people are exposed to a poisonous substance every year in the US, and many are children under five (AAP). Plants are a meaningful slice of that number. And in 99.2% of poison center cases involving children under six in 2024, the exposure was accidental (America’s Poison Centers). Nobody handed a baby a dieffenbachia leaf. They just turned their back for a minute.

The Plants Most Likely to Hurt a Crawling Baby

Some toxic plants are obscure. These are not. The ones below show up in living rooms, offices, and gift deliveries across the country.

Dieffenbachia (also called dumb cane) is probably the most common toxic houseplant in American homes. It contains calcium oxalate crystals that cause immediate, intense burning in the mouth and throat. A baby who chews a leaf will drool, cry, and may have trouble swallowing. In rare cases, swelling can affect the airway. It looks lush and tropical and thrives in low light, which is exactly why it’s everywhere.

Philodendron works the same way. Same calcium oxalate mechanism, same oral burning, same risk profile. Heart-leaf philodendron is one of the most widely sold houseplants in the US. It’s also one of the most frequently involved in pediatric plant exposure calls.

Pothos is often confused with philodendron and carries similar toxicity. It’s the trailing vine you see in every coffee shop and dentist’s office. It’s nearly impossible to kill, which is part of why it’s so popular. It’s also not safe for a baby to mouth.

Oleander is in a different category entirely. This one contains cardiac glycosides. Ingestion can cause heart rhythm problems, vomiting, and in serious cases, life-threatening cardiac effects. The AAP recommends removing it from homes with young children, full stop. If you have oleander indoors or in an accessible outdoor area, it needs to go.

Lilies: A Specific and Serious Risk

Peace lilies are a staple of office gift baskets and sympathy arrangements. They’re elegant, they filter air, and they’re toxic enough that any suspected ingestion in a child under three warrants immediate medical evaluation.

Peace lilies and Easter lilies contain compounds that can cause kidney damage. The amount of leaf material required to cause harm is small. This is not a "they’d have to eat a lot of it" situation. The AAP recommends removing lilies from homes with babies and toddlers rather than relying on placement to keep children safe.

In my experience, "high shelf" is not a permanent solution for a child who is actively learning to climb. A toddler can reach and pull down plants faster than most parents expect.

If you have lilies in your home and a baby under three, remove them. Rehome them with a friend, donate them, or compost them. The plant is replaceable.

Sago Palm, Caladium, and Other High-Risk Decoratives

Sago palms look like miniature tropical trees and are sold at garden centers and big-box stores. They are extremely toxic. Every part of the plant contains cycasin, a compound that can cause severe liver damage. Ingestion of even a single leaflet can be dangerous. If a sago palm is in your home, it needs to be relocated somewhere a toddler cannot reach, and that means inaccessible, not just on a high shelf.

Caladiums are popular for their bold, patterned leaves. They’re frequently sold as seasonal décor. They contain calcium oxalate and other irritants that cause mouth pain, drooling, and GI distress. Same family of risk as dieffenbachia, similar presentation.

Crotons are another common gift plant, with waxy, multicolored leaves. The sap is irritating to skin and mucous membranes. A baby who mouths a croton leaf may develop oral irritation and vomiting.

Daffodils are worth flagging separately because they come into homes as cut flowers and bulb arrangements, especially in spring. The bulbs are the most toxic part, but the leaves and stems also contain lycorine, which causes vomiting and diarrhea. If you’re buying spring flower arrangements, keep them out of reach and dispose of them before they drop leaves.

Seasonal Plants Parents Often Overlook

Holiday season brings a fresh wave of toxic plants into homes that may otherwise be plant-free.

Poinsettias have a reputation for being more toxic than they are, but they still cause oral irritation and vomiting if ingested. Not a plant to leave at floor level with a crawler.

Holly is more serious. The berries are appealing to children and contain saponins that cause vomiting, diarrhea, and in larger amounts, more significant effects. Holly branches used as seasonal décor should stay out of baby-accessible rooms.

Mistletoe is the most dangerous of the holiday trio. Berries and leaves both contain toxic lectins. Keep it out of reach, or skip it.

When hosting holiday gatherings, brief whoever’s bringing decorations before they arrive. It takes one text.

Gift Plants: Inspect Before You Display

Baby showers, new-home gifts, get-well arrangements. Plants arrive as gestures of care, and most people giving them have no idea whether they’re safe for a home with a mobile infant.

Before any gifted plant goes on display, look it up. The ASPCA’s toxic plant database and Poison Control’s online resources both allow you to search by common name. If you can’t identify the plant, photograph it and contact your local nursery or Poison Control before putting it anywhere in the house.

This is not paranoia. It’s a two-minute check.

Spaces Beyond Your Own Home

Poisoning often happens in less familiar environments where supervision is less consistent. Grandparents’ homes, childcare settings, and neighbors’ houses may have plants that your home doesn’t.

When a child starts spending time in a new caregiver’s home, walk through the rooms and point out plants that need to move. Most caregivers are receptive once the risk is explained.

Give caregivers a short list of the plants you’re concerned about. Better yet, share a photo reference. Poison Control’s website has printable resources designed for exactly this purpose.

What to Do If You Suspect Ingestion

Call Poison Control immediately: 1-800-222-1222 (24/7, free, US national hotline). Don’t wait for symptoms. Some toxic plant effects appear within minutes. Others take hours. The specialist on the line will ask for the plant name and an estimate of how much was ingested. If you don’t know the plant’s name, a clear photo can help with identification.

Do not induce vomiting unless Poison Control or emergency services specifically instruct you to. For some plant toxins, vomiting makes things worse.

If your child is having difficulty breathing, is losing consciousness, or is having seizures, call 911 first.

Keep the plant itself or a sample of it available. Identification speeds everything.

Safe Alternatives Worth Knowing

Removing toxic plants doesn’t mean living without greenery. Several common houseplants are considered non-toxic to children and widely available.

• Spider plants are hardy, propagate easily, and are non-toxic.
• Boston ferns add the lush look of tropical plants without the risk.
• African violets are compact, flower reliably, and safe for babies.
• Parlor palms give you the tropical aesthetic of a sago palm without the toxicity.

Before buying any new plant, run the name through Poison Control’s online tool or the ASPCA database. Make it a habit. It takes less time than reading the care tag.

A Practical Audit, Room by Room

The most useful thing you can do today is walk through your home with a critical eye. Not just the obvious rooms. Check the bathroom windowsill, the bedroom corner, the hanging basket in the kitchen. Check what’s at toddler-reachable height and what’s at climbing height, because those are two different measurements and both matter.

Each year, an estimated 60,000 or more children under five are treated in U.S. emergency departments for unintentional poisoning (CPSC). Plants are one piece of that picture, and they’re one of the easier pieces to address. You can remove a plant today. You can rehome it, compost it, or replace it with something safe before your baby’s next nap.

The audit takes twenty minutes. Write down every plant, look up every name you’re not certain about, and make decisions from there. That list is your starting point.
