19 Toxic Plants Parents NEED To Know About

As a parent, one of the many things we learn about is how to protect our children from unnecessary harm. We would do just about anything, to prevent an electric shock, an injury, or an accidental choking. We spend countless hours and dollars, attempting to “baby proof” our homes and our lives. We lock up our cleaning supplies, cover our electrical outlets, remove plush items from cribs, put locks on our toilets, and toss out anything too small for a baby to play with.

If you’ve ever had the sinking feeling, that you have forgotten something very important, you just might be right. Rarely do we see plants included on the many, long lists of baby proofing musts. Most parents have no idea, that many simple plants, flowers, and weeds found in their homes, gardens, and yards are potentially harmful and even fateful if ingested by your little one.

Some of these plants are easy to remove from the home, to avoid the risk of your child ingesting them. Others are not so easy to eliminate, and you may not even realize they are there, until you or your curious baby stumble upon them. Others are common garden plants that you may wish to keep for beauty’s sake or for health benefits. Awareness and diligence are vitally important, to preventing an accidental poisoning or allergic reaction.

Below, we have compiled a list of common plants that are especially dangerous for children. The best way to prevent an emergency is to identify the harmful plants and to keep your child away from them. Next, it is important to recognize the warning signs of poisoning and to get your child to emergency medical services as soon as possible when you suspect that they have eaten something they should not have. Because the treatment methods for plant poisonings vary so widely, it is important not to give your child a drink or to attempt to induce vomiting. In some cases, this can make the condition worse. The best thing you can do is remove any remaining pieces from their mouth and hands, and to get a clipping or a sample of whatever it was that your child ate, to give to the doctor. Contact poison control for detailed instructions on how to handle the symptoms while you are enroute to or are waiting for the arrival of a medical team.

Mostly, when a very large amount of leaves (1 pound or more) are consumed, or when a large amount of unripe and uncooked green tomatoes are eaten, there is a risk of illness associated with poisoning. The main reason for concern is because the tomato plant is closely related to both the night shade plant, and the potato plant, which have proven to be toxic. In high concentrations, consumption of the tomato leaves or of the raw, unripe fruit, may lead to gastrointestinal problems, liver, or heart damage.

Toxic Parts: The leaves and raw unripe fruit.

This popular plant is incredibly dangerous if ingested, as is often found to be drooping towards the ground due its heavy head of flowers. This poses a particular risk to crawlers and toddlers, who can quickly reach the plants, and who are especially susceptible to the toxins due their small body size.

Threat: The plant and the flowers contain hydragin, a poison that will cause shortness of breath, dizziness, fainting, and increased pulse when ingested. In addition, a rapid drop in blood pressure may occur, potentially causing convulsions or death.

Toxic Parts: The entire plant is deadly if consumed, especially the flower buds.

7 Oleander (Pink or Yellow)

What is it? A flowering shrub with pink or yellow flowers. Oleander is especially toxic and is better off removed or relocated if you have young and wandering children.

Children with respiratory allergies should not be exposed to eucalyptus plants.

Toxic Parts: Leaves and bark, as well as the oil.

5 Daffodils

What is it? A spring bulb flower recognizable for its cup or trumpet like flowering parts. The blooms are most often white, yellow, or a combination of both. For the most part, this spring flower isn’t too dangerous, unless the bulb is consumed. Keep bulbs in storage out of the reach of children. Young kids who are at risk for putting the bulb or flowers in their mouth, should not be allowed to help with planting, moving, or digging up daffodils. It is best to move these flowers away from areas where children play or dig. When relocating gardens take extra precautions not to mix up flower bulbs with onion bulbs, as they can have a similar appearance.

Threat: When ingested, severe irritation of the mouth may occur, as well as vomiting, diarrhea, seizure, and altered heart function. The symptoms are usually not life threatening and resolve within a few hours.

Toxic Parts: All parts of the plant, but mostly the bulb.

4 Mushrooms and Toadstools

What is it? Poisonous and non-poisonous mushrooms or toadstools often grow in the same space. It is very difficult to tell them apart. Therefore, it is best to avoid eating any mushroom that you find outdoors, unless you are certain about what it is. Children are especially likely to find any variety of mushroom growing in the soil, grass, or even gardens. It is important to explain to children that wild mushrooms are not the same mushrooms that they may see being used in the kitchen for cooking purposes. Carefully monitor babies and toddlers who can’t understand the difference. Older kids and adults should never attempt to eat any mushrooms that they are not familiar with.

Threat: Even eating just a tiny amount of some mushrooms can cause illness or death. The symptoms may be delayed for several hours after consumption. Symptoms vary depending on the type of mushroom, the size of the person who has consumed it, and the amount that was ingested.

Toxic Parts: All parts of the plant.

3 Water Hemlock

What is it? This wildflower is commonly found intruding on areas with gardens, meadows, pastures, or streams. Sometimes it is viewed as invasive weed. It is characterized by small white clusters of flowers in umbrella like clusters. Be careful not to confuse this plant with similar looking plants like wild parsnips, herbs, or medicinal plants. Many accidental poisoning occur by ingesting an incorrectly identified plant.

Threat: The USDA calls this “the most violently toxic plant that grows in North America." This plant is capable of causing death within 15 minutes of ingestion. It contains a poison called cicutoxin that quickly attacks the central nervous system, causing severe seizures and convulsion that lead to suffocation and heart attack, causing death.

Toxic Parts: The whole plant, especially the roots of a young plant. The most poisonous element is the brown or straw colored liquid that is released when the plant is broken or cut.

2 Poison Ivy, Poison Oak, and Poison Sumac

What is it? All three of these are vines with prominent leaves that grow in the woods or in marshy areas. Sometimes they appear as a loose vine growing on the ground or around tree trunks, or they may grow as a shrub or a tiny tree. While they are most common in forests, they can also be found along fences, among other bushes, or growing up trees in your yard. Take care to wear long sleeves, pants, shoes, and socks when making treks into wooded or marshy areas. Point the plants out to your kids, so they are not tempted to pick the often easy to reach, and sometimes brightly colored leaves. Wash any potentially contaminated clothing promptly, and shower before resuming normal activities throughout the home.

Threat: The plant releases a long lasting oil, urushiol that causes an itchy, blistering rash if it touches the skin. The oil can be released by direct contact, as well as by simply brushing against the plant. The oils can also be transferred to people from clothing and pets that are contaminated with the toxin.

Toxic Parts: Any part of the plant, especially the leaves.

1 Other Harmful Ones

This list is only a small compilation of the potentially harmful plants. There are hundreds or even thousands of mild to lethally dangerous plants that pose a risk to children and humans. Is it important for the safety of your family, and especially for young children, to be aware of all of these types of plants. Young children should not be left unsupervised to play and explore outside. Curious children with small body mass are often more susceptible to the toxins found in poisonous plants. They are more likely to put things into their mouths that older children and adults who not consider fit for consumption. Always monitor your children, teach them about the dangers of eating non-food items. Always be aware of potentially harmful plants at home, present in indoor planters, in parks you frequent, and in new locations alike.
