Plants That Are Toxic to Pets: What Bay Area Gardeners Need to Know
Our furry companions are curious by nature—and that curiosity can sometimes lead them to nibble on the wrong plant. In the Bay Area, where gardens flourish year-round, it’s important to know which plants can pose a risk to dogs and cats.
Whether you're planting in containers, creating a lush landscape, or adding houseplants to your indoor space, this guide will help you keep your pets safe while enjoying a beautiful garden.
🚫 Common Toxic Plants to Watch Out For
These popular plants may thrive in our Bay Area climate, but they can be harmful—or even fatal—if ingested by pets:
- Sago Palm – Highly toxic to both dogs and cats; all parts, especially seeds, are dangerous.
- Oleander – A fire-resistant plant often used in California landscapes, but extremely toxic if eaten.
- Lily (many varieties) – Cats are especially sensitive; even a small amount can cause kidney failure.
- Azalea – Ingestion can lead to vomiting, diarrhea, and in severe cases, coma or death.
- Foxglove – Stunning but toxic; contains cardiac glycosides that affect the heart.
- Autumn Crocus – Different from spring crocus, it can cause serious internal issues.
- Cyclamen – Popular in winter containers, but tubers are especially toxic to pets.
- Euphorbia species (including Pencil Cactus and Crown of Thorns) – Sap can irritate skin and is harmful if swallowed.
