Poisonous Plants to Pets
Thank you to the Humane Society of America and Proven Winners for this information.

Four-legged companions enjoy the outdoors as much, or more, as their human friends. If you share a yard with a pet, use containers to keep fragile flowers out of harm's way, and plant rugged perennials, such as Ajugas, Heuchera, and Ivies in areas with heavy paw traffic.

While plants add a touch of color and fragrance to our daily lives, some can be dangerous to our pets. Keep your pets in mind when creating your outdoor living space for your family. Poisonous plants produce a variety of toxic substances and can cause reactions ranging from mild nausea to death.

Below is a list of some of the common plants that may produce a toxic reaction with your pet. This list is intended only as a guide to plants that are generally identified as having the capability for producing a toxic reaction.
