Plant safety guide

Is Hydrangea safe for pets?

Hydrangea (Hydrangea spp.) is listed here as a Toxic plant for dogs, cats, and rabbits. Hydrangea flowers, leaves, and buds can cause digestive upset when pets eat plant material.

If your pet may have eaten this plant: remove access, identify the plant, estimate the amount and time eaten, and contact your veterinarian or a pet poison hotline. Do not induce vomiting unless a veterinary professional tells you to.

Symptoms to watch for

vomiting
diarrhea
lethargy
depression

Symptoms can vary by pet size, amount eaten, plant part, and individual sensitivity. When in doubt, use the emergency guidance rather than waiting.

What to do if your pet ate it

Remove access, identify how much may have been eaten, and call a veterinarian if symptoms appear or a meaningful amount was swallowed.

For urgent concerns, call your veterinarian, ASPCA Animal Poison Control at (888) 426-4435, or Pet Poison Helpline at (855) 764-7661. Fees may apply.

Safer plant alternatives

These plants are commonly used as safer swaps in pet homes, but even non-toxic plants can cause stomach upset if a pet eats a large amount.
