A variety of indoor plants sit inside a sunny, brightly lit room.Indoor plants brighten our homes, and outdoor gardens bring joy to our neighborhoods, but some plants can be dangerous, especially to young children and pets. At the Iowa Poison Control Center, we want to help you keep your family safe from accidental plant poisonings, whether indoors or outside.

Why Plant Safety Matters

Young children are naturally curious and often explore by putting things in their mouths. Unfortunately, many common household and outdoor plants contain parts that can be toxic if chewed or swallowed. Even plants that are considered “nontoxic” can cause stomach upset or allergic reactions in sensitive individuals. With a few simple precautions, you can greatly increase child safety and reduce the risk of plant-related poisonings.

Easy Safety Tips to Prevent Plant Poisonings

Help prevent indoor and outdoor plant poisonings with these simple steps:

  • Keep plants out of reach to ensure child and pet safety.
  • Label all common plants with their botanical or scientific names so you can look them up quickly. Bring unknown plants to a nursery or garden center for assistance with plant identification.
  • Teach kids never to eat berries, wild mushrooms, or any part of a plant, including leaves, flowers, stems, and seeds.
  • Don’t assume a plant is safe just because wildlife eats it.
  • Avoid jewelry or crafts made from seeds or beans that may be toxic.
  • Save the Poison Help Hotline Number: 1-800-222-1222. Call the Poison Control Center immediately if you suspect a poisoning. Symptoms may be delayed, so don’t wait.
