Are Hibiscus Poisonous?

Hibiscus is a flowering perennial shrub that features large tropical-looking flowers. This plant is grown for its gorgeous summertime blooms, but it is understandable to be concerned about safety when bringing plants into your outdoor space or home. Hibiscus is not poisonous to humans, and it is typically safe for dogs; however, the plant does pose a risk to cats. 


Are Hibiscus Poisonous to Children

No part of the Hibiscus plant, the leaves or the flowers, are poisonous to humans, so it is safe to have the plant around children, toddlers, and babies.

Are Hibiscus Poisonous to Dogs

Most varieties of Hibiscus are not toxic or poisonous to dogs; although, one type, the Rose of Sharon, is toxic to dogs. If your furry friend were to eat large quantities of leaves or flowers from a Rose of Sharon, they might experience an upset stomach, nausea, vomiting, and possibly diarrhea.

Are Hibiscus Poisonous to Cats

Hibiscus are poisonous to cats. The blossoms and stems are toxic, and if consumed, a cat may experience vomiting, diarrhea, and loss of appetite. The symptoms usually subside after 48 hours, but if your feline friend is still sick after 48 hours, or if your cat stops drinking water at any point, then you should consult a vet.

Are Hibiscus Poisonous to Other Animals

Some varieties of Hibiscus are poisonous to animals. If you are unsure about a plant's toxicity, limiting your pets' or animals' exposure is generally best. It is a good idea to monitor your pet for signs of illness or dehydration if you suspect your animal has eaten part of a Hibiscus.
