Houseplant Safety for Babies: Complete List of Toxic and Safe Plants

Every year, an estimated 60,000+ children under five are treated in U.S. emergency departments for unintentional poisoning (CPSC). A meaningful share of those calls to Poison Control involve plants. Not medications. Not cleaning products. Plants sitting on windowsills and shelves, looking harmless, while a baby works through the developmental imperative to put everything within reach directly into their mouth.

I learned this the hard way when my younger daughter, at around 10 months, made a beeline for the pothos trailing off our bookshelf the moment I set her down on the floor. She had a fistful of leaves before I crossed the room. Pothos is on the "mildly toxic" list, which meant a call to Poison Control, a tense 20 minutes, and a complete rearrangement of every plant in the house. It could have been worse. We had a philodendron two feet away.

This guide identifies which plants are dangerous, which are overhyped, which are safe, and how to manage your home’s plant situation before your baby starts crawling.

Why Houseplants Are a Real Poisoning Risk

Babies and toddlers explore the world orally. That’s not a parenting failure. It’s developmental biology. A 9-month-old mouthing a leaf is doing exactly what 9-month-olds do. The problem is that many common houseplants contain compounds that cause anything from mild oral irritation to cardiac arrhythmias, depending on the plant and the amount ingested.

The AAP recommends removing or securing any plant a child can reach. That guidance is broader than most parents expect. "Can reach" includes plants on low shelves, trailing plants whose leaves hang at floor level, and any plant a newly mobile baby might pull down by grabbing a pot or a dangling vine.

More than 99% of poison exposures in children under 6 in 2024 were accidental (America’s Poison Centers). Nobody puts a toxic plant in front of a baby on purpose. These incidents happen because the plant was there, the baby was curious, and the supervision gap was 30 seconds long.

The Most Dangerous Houseplants

These plants belong out of your home entirely if you have a baby or toddler. Not on a high shelf. Not behind a gate. Out.

Oleander is one of the most toxic plants commonly sold as an ornamental. Every part of it, including the leaves, flowers, and stems, contains cardiac glycosides that can cause arrhythmias. Ingestion of even a small amount warrants emergency care.

Sago palm is popular as an indoor and patio plant, and it is extremely dangerous. The seeds contain cycasin, a compound that causes severe liver failure. This one is also highly toxic to pets, which matters if you have both a baby and an animal in the house.

Dieffenbachia, sometimes called dumb cane, is one of the most common houseplants in American homes. It contains calcium oxalate crystals that cause intense burning and swelling in the mouth and throat. Severe cases can cause enough swelling to interfere with breathing. It’s sold everywhere, it looks benign, and parents often have no idea it’s dangerous.

Philodendron contains the same calcium oxalate crystals as dieffenbachia. The reaction is typically less severe but still causes significant oral pain and irritation. Given how common philodendrons are in homes with trailing vines at accessible heights, this one deserves particular attention.

Lily of the Valley causes cardiac arrhythmias and gastrointestinal distress. It’s sometimes brought indoors as a cut flower or small potted plant in spring. Keep it out.

If any of these are currently in your home, I’d encourage you to rehome them now rather than after the next developmental leap.

The Lily Situation Is More Complicated Than You Think

Parents hear "lilies are toxic" and assume all lilies are equally dangerous. They’re not, and the distinctions matter.

Peace lilies are extremely common houseplants. They contain calcium oxalate crystals and cause oral irritation, drooling, and difficulty swallowing. Unpleasant. Rarely life-threatening in small exposures. Still worth keeping out of reach.

Easter lilies and tiger lilies are a different category entirely. True lilies in the Lilium genus are severely toxic to cats, causing acute kidney failure from even small exposures. Their toxicity profile in humans is less extreme but still warrants caution. If you have both a baby and a cat, these plants should not be in your home.

Calla lilies also contain calcium oxalate and cause oral irritation similar to peace lilies.

The practical takeaway: no lily of any kind should be within reach of a crawling baby. The severity varies, but none of them belong on the floor.

Mildly Toxic Plants: Still Not Floor-Level Plants

Several very popular houseplants fall into a "mildly toxic" category. This framing sometimes leads parents to underestimate the risk. "Mild" refers to the toxicity profile in typical small-exposure scenarios. It does not mean safe.

Pothos causes oral and throat irritation, drooling, and vomiting. Most exposures resolve without emergency intervention. But a baby who swallows a piece of leaf can choke on the plant material itself, separate from any chemical toxicity.

Snake plants (also called mother-in-law’s tongue) cause nausea, vomiting, and diarrhea in larger amounts. They’re low-maintenance and widely recommended as beginner plants, which means they’re in a lot of homes.

ZZ plants contain calcium oxalate and should be treated like pothos: not dangerous enough to panic over a small exposure, but not a plant you want accessible to a baby who mouths everything.

Aloe vera causes gastrointestinal upset if ingested. Many parents keep it for its topical uses and assume it’s safe because it’s "natural." It isn’t safe to eat.

If a plant causes any symptoms at all when ingested, it doesn’t live below shoulder height in a room with babies.

Safe Plants for Homes With Babies

These plants have no significant toxicity concern if a baby mouths or ingests them. That doesn’t mean you want your child eating houseplants, but these choices eliminate the poisoning risk.

Spider plants are non-toxic and nearly indestructible. They’re one of the few plants I kept at accessible height after my younger daughter started pulling up to stand, because I knew the worst outcome was a mouthful of plant fiber.

Boston ferns are non-toxic and safe for homes with both babies and pets. They need humidity and indirect light, but they’re a solid choice for a hanging planter in a nursery.

African violets are non-toxic and small enough to keep on a windowsill where a baby can’t reach them easily. A good option for parents who want flowering plants.

Bamboo palm is non-toxic and works well as a larger floor plant if you want greenery in a living space. It’s also on NASA’s air-purifying plant list, which is a bonus.

Orchids are non-toxic. They’re also usually small and kept on countertops, which naturally puts them out of reach.

Areca palm is non-toxic and pet-safe.

If you’re rebuilding your plant collection after a baby arrives, these are the ones to start with.

The Soil and Fertilizer Problem Nobody Talks About

The plant itself is only part of the hazard. Soil and what’s in it present a separate set of risks.

Chemical fertilizers, pesticides, and fungicides can be toxic if ingested. If you’ve treated a plant with any of these products, the soil carries residue. A baby who digs in a pot and then puts their hands in their mouth is getting a dose of whatever you last applied.

Soil also harbors bacteria. E. coli and other pathogens can be present in potting mix, particularly if you’ve used compost-based soil or if the pot has been sitting in standing water. This isn’t hypothetical. It’s a reason to treat soil access the same way you treat access to the area under the kitchen sink.

The fix isn’t complicated. Use plant stands, room restrictions, or baby gates to keep babies out of rooms with floor-level plants entirely. A gate across the sunroom doorway is more reliable than watching a baby every second. And if you fertilize or treat plants with any chemical product, keep the baby out of that room until the soil is dry and the plant has been watered through at least once.

Hanging Planters: Helpful, But Not a Complete Solution

Hanging planters reduce access for young babies. They do not eliminate the risk for older babies and toddlers.

A 14-month-old who can pull to stand will grab a trailing vine. A 20-month-old who has figured out how to push a stool can reach a lot. And a pot that isn’t secured properly can come down on a child who pulls the wrong thing.

If you use hanging planters, secure them to studs, not just drywall. Use hooks rated for several times the weight of the pot when fully watered. Trim any plant material that dangles within arm’s reach of a standing toddler. And check the hardware every few months. Hooks work loose over time, especially in humid rooms.

I moved all my hanging plants to a single room with a gate after my older daughter figured out she could use her toy basket as a step stool. She was 22 months. I had maybe a week between "can’t reach it" and "definitely can reach it."

Seasonal and Holiday Plants

Poinsettias have a reputation for being highly toxic that outpaces the actual risk. They cause mild gastrointestinal upset and oral irritation in most cases. The severe toxicity claims are largely overblown. That said, keep them out of reach. "Mild" still means a sick baby and a call to Poison Control.

Amaryllis causes vomiting, abdominal pain, and in larger amounts, more serious symptoms. It’s a common holiday gift. Keep it on a high shelf or out of the house entirely during the months it’s in bloom.

Mistletoe is more toxic than its holiday-decoration status suggests. The berries cause gastrointestinal distress and, in larger amounts, cardiovascular effects. Keep it out of reach or skip it.

Before you bring any decorative plant into your home during the holidays, spend two minutes verifying its toxicity status. The ASPCA plant database and Poison Control’s website are both useful resources.

Latex-Producing Plants and Allergic Reactions

Ficus and rubber plants produce latex sap. For children with a known latex sensitivity, skin contact with the sap can trigger a reaction, and ingestion is a more serious concern. If your child has had any latex-related reactions, remove these plants from the home entirely.

Even without a known sensitivity, the sap from these plants causes skin irritation in many people. It’s worth wearing gloves when pruning or repotting them, and keeping them out of reach regardless.

Keep Plants in Good Condition

A deteriorating plant sheds more leaves. Mold grows in overwatered soil. Pests, particularly fungus gnats, are attracted to damp potting mix and a baby will absolutely try to eat a bug.

Inspect your plants regularly. Discard any plant showing significant mold, root rot, or pest infestation. A plant that’s declining isn’t just an aesthetic problem. It’s producing more accessible plant material and potentially more contamination risk at floor level.

What to Do If Your Child Ingests a Plant

Call Poison Control: 1-800-222-1222 (24/7, free, US national hotline). Do this immediately, before symptoms appear. Do not induce vomiting. Do not wait to see if anything happens.

Have the plant name ready if you know it. Take a photo of the plant if you don’t. Tell them approximately how much your child may have ingested and your child’s weight. Poison Control will tell you whether you need to go to an emergency room or whether you can manage at home.

If your child is having difficulty breathing, has significant swelling in the mouth or throat, or is losing consciousness, call 911 instead.

Approximately 3 million U.S. poisoning exposures occur annually, with young children disproportionately represented (AAP). Poison Control handles plant ingestions routinely. They are the right first call, and they will tell you exactly what to do.

A Note on Behavioral Expectations

Teaching a baby not to touch plants does not work. The developmental capacity for consistent rule-following around environmental hazards doesn’t come online reliably until well past 18 months, and even then it’s inconsistent under distraction or fatigue. Physical barriers and plant removal are the only reliable strategies for children under two. For toddlers over two, barriers remain more reliable than behavioral expectations.

This is not a criticism of anyone’s parenting. It’s how child development works. Redesign the environment. Don’t rely on the child to manage the risk.
