Home » Gardening Info » Poisonous Plants (for Pets)

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.

I'm so GLAD I found your web site! I enjoy making my own containers, but I'm not always sure about what flowers to put in them. It's much easier to go to your web site, click on the combination searches, look through the recipes, choose the ones I like best, and then make my own. It's also more convenient than trying to decide at a greenhouse. Thank you! Kim, IL
