Avoiding common landscaping plants, even indoor plants, which can be dangerous to children and pets. Poison control warns of these particularly toxic plants.




by Staff


Dangerous plants should never be within reach of puppies or children and that includes outside landscaping plants.


You would never allow a three-year old child unsupervised access to the yard or garden but it's not uncommon for dogs, particularly puppies, to be poisoned by plants in your own yard!


Veterinary toxicologist Dr. Safdar Khan warns that many plants "have the potential to cause serious, even fatal systemic effects when ingested.”


The ASPCA Animal Poison Control Center lists the five most potentially dangerous plants to pets.


We've added photos to help you recognize toxic plants.


Poison proof your yard, then print this out and save it in your pet's folder or his records notebook so you can find it you ever suspect your dog has been poisoned.

Lilies are beautiful but dangerous to children and pets* LILIES, rank number one in dangerous plant can volume at the APCC, and are highly toxic to cats. Says Khan, “It is clear that even with ingestions of very small amounts, severe kidney damage could result.” An owner in Pennsylvania lost her cat to kidney failure from ingesting only a small portion of an Easter lily. Lilies are beautiful but dangerous plants!


Toxic Azaleas are very popular in the south.* AZALEAS, indigenous to many eastern and western states and commonly used in landscaping, contain substances that can produce vomiting, drooling, diarrhea, weakness, and central nervous system depression. Severe cases could lead to death from cardiovascular collapse. Enjoy the colorful hardy Azalea but limit use to restricted areas.


* Frequently used as an ornamental plant, OLEANDER contains toxic components that can cause irritation of the gastrointestinal tract, hypothermia, and potentially severe cardiac problems. The stunning white flowers belie this plant's toxicity. It may be best for front yards where children and pets do not play.


Sago Palm can be deadly to dogs* Also a popular ornamental plant, SAGO PALM, can potentially produce vomiting, diarrhea, depression, seizures, liver failure, and even death. One pit bull terrier in Florida became ill and subsequently died from liver failure after chewing on the leaves and base of a sago palm in his yard. Bull Terriers like to walk under the leaves (Bullies are funny that way) and although the trance-like behavior is not to be confused with a toxic reaction, they are best discouraged.


Castor Bean plants are a particularly dangerous plant because they are very attractive to pets and children* Although all parts of the CASTOR BEAN plant are dangerous, the seeds contain the highest concentration of toxins. Ingestion can produce significant abdominal pain, vomiting, diarrhea, and weakness; in severe cases, dehydration, tremors, seizures, and even death could result.


For more on these dangerous plants, please visit ASPCA online. If you suspect that your pet may have consumed one of these - or any other potentially toxic substance - please contact your veterinarian or the Animal Poison Control 24-hour hotline at (888) 426-4435.
