Pet dangers lurk in the garden
After a long winter, it’s great to see the spring flowers starting to bloom. But the ASPCA warns that some of the most popular flowers and shrubs can pose a hazard to our pets. The Animal Poison Control Center received nearly 8,000 calls for plant poisoning in 2008.
Here is a ASPCA list of some common plants that can be hazardous to your pet’s health:
Lilies
Members of the Lilium spp. are considered to be highly toxic to cats. Even very small amounts of the plant can cause severe kidney damage.
Tulip/Narcissus bulbs
The bulbs contain toxins that can cause intense gastrointestinal irritation, drooling, loss of appetite, depression of the central nervous system, convulsions and cardiac abnormalities.
Azalea/Rhododendron
These bushes contain substances known as grayantoxins, which can produce vomiting, drooling, diarrhea, weakness and depression of the central nervous system in animals. Severe azalea poisoning could ultimately lead to coma and death from cardiovascular collapse.
Cyclamen
Cylamen species contain cyclamine, but the highest concentration of this toxic component is typically located in the root portion of the plant. If consumed, Cylamen can produce significant gastrointestinal irritation, including intense vomiting. Fatalities have also been reported in some cases.
Yew
Yews contain a toxic component known as taxine, which causes central nervous system effects such as trembling, incoordination, and difficulty breathing. It can also cause significant gastrointestinal irritation and cardiac failure, which can result in death.
Amaryllis
Amaryllis contain toxins that can cause vomiting, depression, diarrhea, abdominal pain, hypersalivation, anorexia and tremors.
Chrysanthemum
These flowers contain pyrethrins that may produce gastrointestinal upset, including drooling, vomiting and diarrhea, if eaten. In certain cases depression and loss of coordination may also develop if enough of any part of the plant is consumed.
English Ivy
If pets ingest ivy, it can cause vomiting, abdominal pain, hypersalivation and diarrhea.
Peace Lily
The peace lily contains calcium oxalate crystals that can cause oral irritation, excessive drooling, vomiting, difficulty in swallowing and intense burning and irritation of the mouth, lips and tongue in pets who ingest.
Also, gardeners take note: The ASPCA warns that mulch made from cocoa bean shells, can be toxic to dogs.

Comments
Thanks for spreading the word on pet toxicities on your website - so important for pet owners to be aware of the lurking household poisons in(and outside of) their house and garden!
As an ER specialist, I see so many toxicities that owners bring in too late (making it more expensive to treat, with a worse prognosis!). When in doubt, it's so important to call a Poison Control for peace of mind!
I wanted to make you aware of another important resource out there also - Pet Poison Helpline is an additional Animal Poison Control Center, and it's one of the most cost-effective animal poison ($35/case vs. ASPCA's new $60/case) controls out there nowadays. Unfortunately, because animal poison controls are not federal- or state-funded, there is a fee to allow the service to be run 24-7. We provide a similar service, but have the added benefit of veterinary specialists (in internal medicine and emergency and critical care) as part of our staff. You can always call 1-800-213-6680 if you ever have a problem. Thanks for spreading the word!

Yikes! My in-laws have a large garden filled with tulips, I'll definitely keep my eyes out when Scout and Brogan are frolicking in the yard. Great post, I had no idea certain flowers could be harmful.

You do a great job of pointing out some of the more commonly overlooked dangers that lurk in gardens. I have seen many pets come into my clinic suffering from maladies they experienced in the garden. If you are aware of these dangers, you can prevent them.

What can we use as fertilizers without harming the pets?
I would guess you should try for organic, but let's throw it out to the group. Anyone have any ideas?--Liz

Yes - so many common poisonous plants in our garden! I've included a few more listed below

Spring is just around the corner! Plant bulbs are just as excited to break through the ground to add some color to our yards as we are to see some greenery! That said, we need to be aware of the potential dangers spring plants can be for our pets. Here is a list of some of the most common spring plants and their toxicities… so you know how to pet-proof your garden and keep your pet safe!
Tulips and Hyacinth
Tulips contain allergenic lactones while hyacinths contain similar alkaloids. The toxic principle of these plants is very concentrated in the bulbs (versus the leaf or flower), so make sure your dog isn’t digging up the bulbs in the garden. When the plant parts or bulbs are chewed or ingested, it can result in tissue irritation to the mouth and esophagus. Typical signs include profuse drooling, vomiting, or even diarrhea, depending on the amount consumed. There’s no specific antidote, but with supportive care from the veterinarian (including rinsing the mouth, anti-vomiting medication, and possibly subcutaneous fluids), animals do quite well. With large ingestions of the bulb, more severe symptoms such as an increase in heart rate and changes in respiration can be seen, and should be treated by a veterinarian. These more severe signs are seen in cattle or our overzealous, chowhound Labradors.
Daffodils
These flowers contain lycorine, an alkaloid with strong emetic properties (something that triggers vomiting). Ingestion of the bulb, plant or flower can cause severe vomiting, diarrhea, abdominal pain, and even possible cardiac arrhythmias or respiratory depression. Crystals are found in the outer layer of the bulbs, similar to hyacinths, which cause severe tissue irritation and secondary drooling. Daffodil ingestions can result in more severe symptoms so if an exposure is witnessed or symptoms are seen, we recommend seeking veterinary care for further supportive care.
Lilies
There are dangerous and benign lilies out there, and it’s important to know the difference. Peace, Peruvian, and Calla lilies contain oxalate crystals that cause minor signs, such as tissue irritation to the mouth, tongue, pharynx, and esophagus – this results in minor drooling. The more dangerous, potentially fatal lilies are true lilies, and these include Tiger, Day, Asiatic, Easter and Japanese Show lilies – all of which are highly toxic to cats! Even small ingestions (such as 2-3 petals or leaves) can result in severe kidney failure. If your cat is seen consuming any part of a lily, bring your cat (and the plant) immediately to a veterinarian for medical care. The sooner you bring in your cat, the better and more efficiently we can treat the poisoning. Decontamination (like inducing vomiting and giving binders like activated charcoal) are imperative in the early toxic stage, while aggressive intravenous fluid therapy, kidney function monitoring tests, and supportive care can greatly improve the prognosis.
Crocus
There are two Crocus plants: one that blooms in the spring (Crocus species) and the other in the autumn (Colchicum autumnale). The spring plants are more common and are part of the Iridaceae family. These ingestions can cause general gastrointestinal upset including vomiting and diarrhea. These should not be mistaken for Autumn Crocus, part of the Liliaceae family, which contain colchicine. The Autumn Crocus is highly toxic and can cause severe vomiting, gastrointestinal bleeding, liver and kidney damage, and respiratory failure. If you’re not sure what plant it is, bring your pet to their veterinarian immediately for care. Signs may be seen immediately but can be delayed for days.
Lily of the Valley
The Convallaria majalis plant contains cardiac glycosides which will cause symptoms similar to digitalis (foxglove) ingestion. These symptoms include vomiting, diarrhea, a drop in heart rate, severe cardiac arrhythmias, and possibly seizures. Pets with any known exposure to this plant should be examined and evaluated by a veterinarian and treated symptomatically.
In addition…Fertilizers
As we gardeners work on our rose garden, be aware of those fertilizers. While most are not very toxic (resulting in minor gastrointestinal irritation when consumed), some fertilizers can be fatal without treatment. Here are a few ingredients to be aware of so you know what toxins and symptoms to watch out for.
· Blood meal – This is dried, ground, and flash-frozen blood and contains 12% nitrogen. While it’s a great organic fertilizer, if ingested, it can cause vomiting (of some other poor animal’s blood) and diarrhea. More importantly, it can result in severe pancreatitis, which is inflammation of the pancreas. Some types of blood meal are also fortified with iron, resulting in iron toxicity, so make sure to know what’s in your bag of blood!
· Bone Meal – This is made up of defatted, dried, and flash-frozen animal bones that are ground to a powder. This “bone” is also what makes it so palatable to your dog, so make sure to keep your pet from digging in it and ingesting the soil. While this also makes a great organic fertilizer, it can become a problem when consumed as the bone meal forms a large cement-like bone ball in the stomach – which can cause an obstruction in the gastrointestinal tract – resulting in possible surgery to remove it!
· Rose and plant fertilizers – Some of these fertilizers contain disulfoton or other types of organophosphates (OP). As little as 1 teaspoon of 1% disulfoton can kill a 55 lb dog, so be careful! Organophosphates, while less commonly used, can result in severe symptoms [including SLUD signs (which abbreviate for salivation, lacrimation, urination, and defecation), seizures, difficulty breathing, hyperthermia, etc. In some cases, it can be fatal!
· Pesticides/Insecticides – Most pesticides or insecticides (typically those that come in a spray can) are basic irritants to the pet and are usually not a huge concern unless a pet’s symptoms become persistent. Some may contain an organophosphate which can be life threatening when consumed in large quantities. It is always best to speak to a trained medical professional if there are any questions.
· Iron – This is commonly added to fertilizers, and can result in iron toxicity (from ingestion of elemental iron). This is different from “total” iron ingestion, and can be confusing to differentiate.
When in doubt, have a medical professional at Pet Poison Helpline assist you with finding out if the amount ingested was toxic or not. Large ingestions can result in vomiting, bloody diarrhea, and potential cardiac and liver effects.
The best thing any pet owner can do is to be educated on the household toxins (both inside the house and out in the garden!) - that way you make sure how to pet proof your house appropriately. Make sure to keep all these products in labeled, tightly-sealed containers out of your pet’s reach. When in doubt, please feel free to Pet Poison Helpline at 1-800-213-6680 with any questions or concerns if you’re worried that your pet could have inadvertently gotten into anything!
Please feel free to spread the word – feel free to copy this to distribute – spread the word on springtime toxins and help keep your pet safe!

I received an email a few days ago that warned of the dangers of cocoa hull mulch. If a dog or cat chews on the stuff the theobromine (I think it was) can cause seizures and possible death.

We have a large garden in our home. There are Chrysanthemum and Peace Lily plants in garden. They are so beautiful plants. But now I am worry to know that these plants are harmful for pet animals as in my home there are two little puppies and they always play in garden. So I have to remove these plants for them. Well thanks for sharing such nice information on different plants. I like this site as it is very informative.
