10 Spring Plants That Are Dangerous for Pets

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


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.

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 plant’s 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).

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.

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.

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 you’re 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.
