Alphabetical index of poisonous plants

The toxicity of plants

It is vitally important that you know the names of all plants in your home and yard. We suggest that you keep with your plants the name tabs that come with them when purchased. Take unfamiliar plants to a reputable nursery or plant store and have them positively identified.

We cannot identify plants from a phone description.

Contact us immediately if you suspect your pet may have eaten something poisonous. Do not wait for symptoms to appear! Contact us at 530-758-5650 for further help or to arrange an emergency visit.

To see whether or not one of your plants is poisonous (toxic), look it up on this list and check to see what number follows its name. Then read the information after that number in the Toxicity Index in the sidebar. If you have any questions or if your plant is not included on this list, please call Poison Control.
