Some of your indoor plants are just not safe if you have pets or young children, which is a sad but inevitable realization in the road of becoming a plant parent. While many common genera of houseplants are stunning to look at, many of them are moderately or seriously hazardous. Still others, when handled excessively, can irritate the skin.
The good news is that with enough preparation, you can determine which dangerous houseplants to stay away from, evaluate the risk to your family and pets, and still enjoy a lively and stunningly green collection of indoor plants.
Here are 10 toxic houseplants that, while we love them, should be used with caution if your children or pets will have access to them. A word of clarity, though, is in need before we proceed: “toxic is a relative term, and the severity of a reaction will depend largely on the level of exposure (amount consumed), which plant species, and the specifics of your pet. Some poisonous houseplants cause short-lived, acute symptoms (such as vomiting). Some can have more serious, life-threatening effects if swallowed in excess, while others only irritate the skin. This list is by no means intended to be comprehensive, so we strongly advise conducting additional research (ASPCA has a great database for pet owners).
