Butterfly bushes (Buddleja davidii) are popular in gardens because they have bright flowers and attract butterflies and hummingbirds. They are safe for people and animals, but some may worry about risks. This article explains their safety and any concerns you should know.
Are Butterfly Bushes Toxic to People?
Butterfly bushes are not poisonous to people. They are not meant to be eaten, but eating a small amount of the leaves or flowers is unlikely to cause harm. Still, it’s best to stop children from eating any part of the plant. Some sources mention butterfly bush jelly, but if you’re unsure about its safety, avoid it.
Are Butterfly Bushes Toxic to Dogs and Cats?
Butterfly bushes are safe for animals, including dogs, cats, and livestock. Deer also tend to stay away from them. In rare cases, eating a lot of seed pods, berries, or leaves may upset an animal’s stomach, especially smaller pets. One source claims butterfly bushes contain strychnine and are toxic, but there is little proof of this. If your pet seems sick and you think the plant is the cause, call the Pet Poison Hotline at (855) 764-7661 for vet advice.
Butterfly Bush vs. Butterfly Weed
This article is about butterfly bushes (Buddleja davidii), not butterfly weed (Asclepias tuberosa). Butterfly weed is toxic to people and animals. It contains cardiac glycosides, which can cause stomach problems and heart issues if eaten.
Do Butterfly Bushes Have Harmful Chemicals?
There is little information about harmful chemicals in butterfly bushes. Some sources say their seeds may contain something toxic, but the exact compound is unknown. A related plant, Clerodendrum trichotomum, is used in traditional Chinese medicine to lower blood pressure.
Signs of Poisoning
There are no known poisoning symptoms in people or animals from butterfly bushes. But eating a lot may cause mild stomach problems in animals.
Which Parts of the Plant Are Most Harmful?
There is no clear answer to which parts of the butterfly bush are most harmful. Since the seeds may contain toxic compounds, it’s best not to eat them.
What to Do If Poisoning Happens?
Butterfly bush poisoning is rare and mild. If someone or an animal eats a lot and feels sick, contact a doctor or vet.
Are Butterfly Bushes Invasive?
Butterfly bushes are safe but can spread too much in some areas. They can mix with wild plants and grow uncontrollably. Choosing special types that don’t spread or managing their growth can help.
Are Herbicides Used on Butterfly Bushes Safe?
Some herbicides used to remove butterfly bushes contain chemicals like glyphosate and triclopyr. These chemicals can harm people, animals, and the environment if used incorrectly. Always read the label and use them safely.
Final Thoughts
Butterfly bushes are beautiful and attract pollinators. They are generally safe for people and animals, with little risk of toxicity. However, some types spread too much and may become a problem. If you have concerns, talk to a doctor, vet, or gardening expert. If you want better plants for local butterflies, consider milkweed, asters, or goldenrod.
