If you’re a parent with a ZZ plant at home, you might wonder about its safety around your little one.
ZZ plants, also known as Zamioculcas, contain calcium oxalate crystals that can be harmful if ingested.
The ZZ plant is toxic to babies and young children, causing symptoms like mouth swelling, irritation, and digestive discomfort if plant parts are chewed or swallowed.
When a baby touches the slimy parts of a ZZ plant and then puts their hands in their mouth, it can lead to swelling and itchiness.
The Children’s Hospital of Philadelphia advises that both adults and children should avoid contact with these plants.
While the toxicity levels are sometimes exaggerated and no long-term harm typically occurs, it’s still important to keep ZZ plants out of reach of curious little ones who might try to taste or touch them.
If a baby accidentally ingests part of a ZZ plant, they might cry, cough, or show signs of discomfort.
In such cases, giving them water and monitoring for any severe reactions is recommended.
For households with babies and toddlers, it may be safer to choose non-toxic houseplants until children are old enough to understand not to eat plants.
What Are the ZZ Plants
The ZZ plant has gained popularity as a houseplant due to its hardiness and attractive appearance. However, it’s important to understand its botanical characteristics and potential toxicity before bringing it into homes with babies.
The ZZ plant, scientifically known as Zamioculcas zamiifolia, belongs to the Araceae family. This plant is native to Eastern Africa, particularly Tanzania and Zanzibar. It evolved in dry, arid conditions, which explains its remarkable drought tolerance.
Unlike many other houseplants, the ZZ plant has developed specialized underground rhizomes that store water. These potato-like structures allow the plant to survive long periods without watering.
The ZZ plant contains calcium oxalate crystals, a compound naturally found in many plants and even in the human body. These crystals serve as the plant’s natural defense mechanism against predators in the wild.
The ZZ plant goes by several common names that reflect its characteristics:
- Zanzibar Gem: Referencing its geographical origin
- Eternity Plant: Highlighting its longevity and resilience
- Aroid Palm: Though not a palm, its appearance resembles one
- Fat Boy: Describing its thick, water-storing stems
Several varieties of ZZ plants exist, each with distinctive features:
| Variety | Description |
|---|---|
| Raven ZZ | Dark purple-black foliage |
| Zenzi | Compact with curled leaflets |
| Zamicro | Dwarf variety with smaller leaves |
| Variegated ZZ | Green leaves with white/cream patches |
The ZZ plant features glossy, dark green leaves that grow on thick stems. Each leaf consists of multiple leaflets arranged in opposite pairs, creating a feather-like appearance. The waxy coating on the leaves gives them a distinctive shine.
This indoor plant typically grows slowly, reaching 2-3 feet in height and width when mature. New growth emerges from the soil as bright green shoots that unfurl into stems topped with leaflets.
ZZ plants rarely flower indoors, but when they do, they produce small, inconspicuous flowers near the base of the stems. These flowers resemble those of peace lilies but are much smaller.
The plant’s thick stems and rhizomes store water, making it extremely drought-tolerant. This adaptation allows the ZZ plant to thrive even with minimal care, making it popular among busy plant owners or those new to houseplants.

Toxicology of the ZZ Plant
ZZ plants contain toxic substances that can cause irritation when ingested or when their sap contacts skin. Understanding how these plants’ toxicity works helps parents make informed decisions about keeping them in homes with babies.
Plant Toxicity Mechanism
The ZZ plant (Zamioculcas zamiifolia) produces toxic compounds as a natural defense mechanism. When the plant is damaged or broken, it releases sap containing irritants. This toxicity serves to protect the plant from being eaten by animals in its native environment.
Despite widespread concerns, ZZ plants have relatively mild toxicity compared to other houseplants. The symptoms are typically temporary and not life-threatening. However, this doesn’t mean they should be accessible to babies or small children.
The toxic effects occur primarily when the plant parts are chewed or ingested. Skin contact with the sap can also cause irritation, especially if the sap touches sensitive areas or open wounds.
Calcium Oxalate Crystals
The main toxic component in ZZ plants is calcium oxalate crystals. These microscopic, needle-shaped crystals are present throughout the plant, including leaves, stems, and roots.
When a baby or child bites into the plant, these crystals can:
- Puncture sensitive mouth tissues
- Cause immediate pain and burning sensation
- Create swelling in the mouth, tongue, and throat
- Trigger excessive drooling
The Children’s Hospital of Philadelphia recommends avoiding contact between children and plants containing calcium oxalate crystals. The intensity of reactions varies between individuals, with some experiencing more severe symptoms than others.
If ingested in large quantities, these crystals may cause stomach discomfort and digestive issues. Fortunately, the unpleasant taste usually prevents consuming large amounts.

Health Implications
ZZ plants contain calcium oxalate crystals that can cause adverse health effects when ingested or when plant sap contacts skin. These crystals are the plant’s natural defense mechanism against predators.
Symptoms of Poisoning
If a piece of ZZ plant is swallowed, several symptoms may appear within minutes. The most common signs include:
- Burning sensation in the mouth and throat
- Swelling of lips, tongue, and oral tissues
- Excessive drooling
- Difficulty swallowing
- Nausea and possible vomiting
Most poisoning cases from ZZ plants are mild and self-limiting. Serious complications are rare because the intense pain usually prevents someone from eating large amounts.
Treatment typically involves rinsing the mouth, drinking milk or water, and using pain relief if needed. In most cases, symptoms resolve within 24 hours without long-term damage.
Skin Irritation Concerns
The sap of ZZ plants can cause contact dermatitis in some individuals. When the plant is damaged, it releases calcium oxalate crystals that may irritate skin.
Symptoms of skin contact include:
- Redness
- Itching
- Burning sensation
- Minor swelling
Wearing gloves when handling ZZ plants is recommended, especially when repotting or pruning. If skin contact occurs, wash the affected area thoroughly with soap and water.

Risk to Babies and Small Children
Babies and toddlers face a higher risk from ZZ plants due to their exploring nature and tendency to put objects in their mouths. Their smaller body size also means toxins can affect them more severely.
Children who touch ZZ plants and then touch their eyes or mouth may experience irritation and swelling. The bitter taste and immediate discomfort usually prevent them from consuming large amounts.
If you have young children, consider placing ZZ plants on high shelves or in rooms where children don’t play unsupervised. Teaching older children not to touch or eat houseplants is also important.
If you suspect your child has ingested any part of a ZZ plant, contact poison control immediately for guidance.
Safety Measures and First Aid
Protecting your baby from ZZ plant toxicity requires both preventative steps and knowing how to respond if exposure occurs. The calcium oxalate crystals in ZZ plants can cause immediate discomfort and potentially serious reactions in infants.
Preventative Steps
Keep ZZ plants completely out of reach of babies and toddlers. Place them on high shelves or in rooms where children don’t play unsupervised. Consider using plant stands that are stable and tall enough to prevent curious little ones from reaching them.
When handling ZZ plants, always wear gloves to prevent skin irritation. Wash your hands thoroughly after any contact with the plant, especially before handling your baby.
Label your plants clearly if you have caregivers or visitors who may not know which plants are toxic. Consider using decorative barriers around floor plants that can’t be moved to higher locations.
Regularly check for fallen leaves, as these contain the same toxic compounds as the rest of the plant and might be tempting for babies to grab or mouth.
Immediate Actions upon Ingestion
If your baby ingests any part of a ZZ plant, remove any remaining plant material from their mouth immediately. Rinse their mouth gently with cool water to wash away irritating crystals.
Offer small sips of milk or water to help soothe irritation, but don’t force liquids if they resist. Avoid giving any food until symptoms subside.
Watch for signs of distress, including:
- Excessive drooling
- Swelling of lips, tongue, or throat
- Difficulty swallowing
- Vomiting
- Signs of pain or discomfort
Apply a cold compress to irritated skin if external contact has occurred. Do not apply creams or ointments unless directed by a medical professional.
When to Contact Poison Control
Call Poison Control (800-222-1222) immediately if your baby has ingested any part of a ZZ plant. This service is available 24/7 and staffed by medical professionals trained to handle toxicity cases.
When calling, be prepared to provide:
- The baby’s age and weight
- Approximate amount of plant material ingested
- Time since ingestion
- Symptoms being displayed

Comparison with Other Houseplants
ZZ plants are one of many houseplants that contain calcium oxalate crystals, which can be toxic if ingested. Understanding how ZZ plants compare to other common houseplants can help parents make informed choices about what to bring into their homes.
ZZ Plant Vs. Similar Toxic Houseplants
ZZ plants belong to the Araceae family, which includes several other common houseplants with similar toxicity concerns.
Pothos and philodendron also contain calcium oxalate crystals and can cause mouth irritation, difficulty swallowing, and stomach upset if chewed or eaten.
Dieffenbachia (commonly called Dumb Cane) is particularly notorious because it can cause swelling of the tongue and throat, potentially interfering with breathing.
Peace lilies produce similar symptoms but tend to be milder than dieffenbachia.
If comparing toxicity levels, ZZ plants fall somewhere in the middle. They’re not as severely toxic as dieffenbachia but can still cause uncomfortable symptoms if ingested.
The main difference is accessibility – ZZ plants have sturdy, thick leaves that are less likely to break off compared to the trailing vines of pothos or philodendron that might be easier for babies to grab.
Non-toxic Alternatives
For households with babies and young children, there are several attractive non-toxic alternatives to ZZ plants.
- Aspidistra lurida (Cast Iron Plant) is extremely durable and non-toxic, making it an excellent substitute with similar low-light tolerance.
- Chamaedorea elegans (Parlor Palm) offers an elegant appearance without toxicity concerns. It thrives in similar indirect light conditions that ZZ plants enjoy.
- Chlorophytum comosum (Spider Plant) is not only safe but actually helps purify indoor air. Its arching leaves with babies at the ends can be visually interesting for children without posing ingestion risks.
Other safe options include Boston ferns, calatheas, and most types of peperomias. These plants provide greenery and beauty without the worry of toxicity if curious babies decide to taste them.
When selecting houseplants for homes with children, consider placing plants on high shelves or hanging them from the ceiling as an extra precaution.
