10 Spring Plants That Are Dangerous for Pets

Spring has finally sprung ó but some of the flowers and plants growing in your garden or blooming in your vases could cause serious harm to your pet.

As a veterinary toxicologist for the ASPCA Animal Poison Control Center and a gardening enthusiast, I often give advice on planting pet-safe gardens ó and with the planting season in full force, itís important for all dog and cat owners to be extra vigilant about keeping dangerous plants out of their homes and gardens. If you suspect your dog or cat has ingested a toxic plant, call the ASPCA Animal Poison Control Center hotline at 888-426-4435 and contact your veterinarian. Itís always better to be safe than sorry.ThinkstockPhotos-501823094 (1)


You may be tempted to decorate your home with a beautiful bouquet of lilies, but doing so could spell trouble for your cat.†Members of the true lily (Lilium) and day lily (Hemerocallis) families have been shown to cause acute kidney failure in felines. Some examples of true lilies include Easter lilies (L. longiflorum), tiger lilies (L. tigrinum) and Japanese Show lilies (L. speciosum). Even a small amount of exposure (a few bites on a leaf, ingestion of pollen, etc.) may result in kidney failure. Cats often vomit within a few hours of exposure and become lethargic.ThinkstockPhotos-508510200 (1)


Usually one of the first plants to bloom in spring, daffodils (Narcissus spp.), which are also known as jonquils, paper whites and narcissus, contain lycorine and other alkaloids that can be poisonous for dogs and cats. The toxins are mostly in the plantís bulb and, if ingested, can lead to vomiting, salivation and diarrhea. If your animal ingests large amounts of the plant, he could suffer from convulsions, low blood pressure, tremors and cardiac arrhythmias (irregular heartbeats).ThinkstockPhotos-489699841 (1)

Sago Palms

Sago palms (Cycads, Macrozamia and Zamia spp.) are often outdoor ornamental plants in warm climates or houseplants in cooler climes. Ingestion of this highly toxic plant can cause liver failure and death in dogs and cats. All parts of the plant are toxic, with the seeds having the highest concentration of toxin. All it takes is one to two seeds to cause clinical signs and possibly death in a dog. Vomiting usually begins within 24 hours, and animals may eventually become depressed and start to seizure. This plant is one of the most toxic, with a mortality rate of around 50 percent.Beautiful flowers of a lily of the valley

Cardiac Glycoside Plants

Plants containing cardiac glycosides include oleander (Nerium oleander), foxglove (Digitalis purpurea) and lily of the valley (Convallaria majalis). Glycosides can slow down the heartbeat and even stop it. These are typically outdoor plants, but the popular and beloved lily of the valley is a common bouquet flower for weddings and holiday gatherings.ThinkstockPhotos-186487777 (1)


Most of the toxins in tulips (Liliaceae spp.) are concentrated in the bulbs, so if your dog is a digger or your cat frequents your flower beds, you should be especially cautious about keeping this flower out of your garden. Signs of toxicity can include vomiting, depression, diarrhea and increased salivation.???????????????


Begonias (Begonia spp.) are popular plants, because they are generally easy to grow, can thrive in many conditions and produce gorgeous blooms. But if youíre a dog or cat owner, begonias need to stay out of your garden. Most of the toxins are concentrated in the tuber or underground stem of the plant and can cause serious burning and irritation of the mouth, tongue and lips; excessive drooling; vomiting and difficulty swallowing.Datura flower seeds and fruit

Jimson Weeds

Also known as devilís trumpet, the†Jimson weed (Datura stramonium) can be moderately toxic to cats and dogs and typically infests farmland and pastures. Accidental ingestion can cause restlessness, drunken walking and respiratory failure.ThinkstockPhotos-78047948 (1)

Grayanotoxin Plants

Ingesting plants containing grayanotoxins (andromedotoxins) can cause vomiting, seizures and cardiac arrest. Sources include rhododendrons and azaleas (Rhododendron spp.), laurels (Kalmia latifolia and Leucothoe davisiae) and Japanese pieris (Pieris japonica). These are typically outdoor plants, but they can be highly toxic for both dogs and cats and deserve extra caution.ThinkstockPhotos-511306030 (1)


You may dream of frolicking through a meadow of buttercups (Ranunculus spp.) with your dog or cat, but should your animal nibble on this flower, it could lead to vomiting, diarrhea, anorexia, excessive salivation and a drunken gait.ThinkstockPhotos-471792331 (1)


A member of the Liliaceae family, the hyacinth (Hyacinthus orientalis) contains dangerous alkaloids that can cause vomiting, diarrhea, depression and tremors in cats and dogs.

Well I never! Being autumn here Ive just finished planting bulbs but didn't realise these favourites of mine are so bad for cats and dogs. What a shame they dont do the same for slugs and snails. Anyone know of a plants that will deter our 4 legged furry freinds? If there is I could plant a boarder around my bulbs. - smile

I called poison control when my lively puppy dashed over to dropped Prozac and I want to know if it would poison him. Be ready with a credit card if you do call them, its not free!

Some of these plants are not only poisonous to pets, but to people as well.
