For Poisoning Questions or Emergencies, Call



Poisonous and irritant plants can be a problem for small children who are curious and take a nibble. Some cats, puppies or other pets may also eat random plants and be at risk for a serious poisoning. Many plants are poisonous to both humans and animals. We recommend knowing the names of the plants in your house and yard and removing the most toxic species from play areas (see the chart below for information about many Florida plants). Callers to poison centers may attempt to send pictures of a plant after a suspected poisoning. The poison center staff may be able to identify the more common varieties. In most cases, absolute identification by having prior knowledge of the plant name or having a professional identify the plant (nursery) is preferred. This can help make a rapid identification and help poison center staff assess the situation. Most plant poisonings do not require hospitalization, and callers receive all the help they need over the phone. Some of the more dangerous plants common in Florida are described below.

For more information about the poisonous and irritant plants of Florida, see our flyer or visit The University of Florida IFAS Extension Program.
