Before bringing a plant into your home, be sure it’s safe for your pets. Some plants are so toxic they should never be kept in homes where animals live (the most hazardous are sago palms and, for cats, lilies). But many plants pose little danger to animals and are good choices for households with pets.
If you need to find out if a plant is safe, the list of toxic and nontoxic plants on the ASPCA Animal Poison Control website is an excellent resource: https://www.aspca.org/pet-care/animal-poison-control/toxic-and-non-toxic-plants.
You can search the list for specific plants, and you can also generate lists of plants that are toxic or not toxic for dogs, cats, or horses. Some toxic and nontoxic plants have very similar common names, so always check a plant’s scientific name.
“Toxic” is a relative term when it comes to plants. Plants listed as toxic might cause anything from mild mouth irritation to death. Even plants listed as nontoxic can cause nausea, vomiting, or diarrhea if they’re eaten. Plants listed as nontoxic should not cause life-threatening illness in animals.
These are a few of the houseplants that are not toxic to dogs and cats, according to ASPCA Animal Poison Control. Scientific names are from the ASPCA and the North Carolina Extension Gardener Plant Toolbox (https://plants.ces.ncsu.edu/).
African violet (Streptocarpus ionanthus)
American or baby rubber plant (Peperomia obtusifolia)
Always check the scientific names of plants called “rubber.” Baby rubber plants aren’t toxic to dogs and cats. Jade plants, sometimes called dwarf rubber or Chinese rubber plants (Crassula ovata), are toxic. Indian rubber plants (Ficus benjamina) are also toxic to dogs and cats.
Boston fern (Nephrolepis exalta)
Some ferns are safe and some aren’t. Boston fern isn’t toxic to dogs and cats, but asparagus fern (Asparagus densiflorus [Sprengeri group]) and some of the ferns that grow outdoors are. Fern palm is another name for sago palm (Cycas and Zamia species), one of the most dangerous plants to have anywhere near an animal.
Cast iron plant (Aspidistra elatior)
Christmas cactus (Schlumbergera species)
Christmas cactus isn’t toxic, but pencil cactus (Euphorbia tirucalli) irritates the mouth and stomach and can cause vomiting.
Gerbera daisy (Gerbera jamesonii)
Gerbera daisies are safe for dogs and cats. Some other daisy-like plants are listed as toxic; these include seaside daisy (Erigeron speciosus), chrysanthemum (Chrysanthemum species), chamomile (Chamaemelum nobile), and, not surprisingly, poison daisy/mayweed (Eclipta prostrata).
Hens and chicks (Sempervivum species)
The small succulent called hens and chicks isn’t toxic. Some other succulents, like jade plants (Crassula species), can be toxic to dogs and cats.
Majesty palm (Ravenea rivularis), parlor palm (Chamaedorea elegans)
Always look up palm species to be sure they’re safe. Majesty, parlor, and several other types of palm are safe for dogs and cats, but sago palm (Cycas and Zamia species) can be deadly.
Phalaenopsis or moth orchid (Phalaenopsis species)
Spider or ribbon plant (Chlorophytum comosum)
Zebra haworthia (Haworthiopsis species)
The zebra plant looks similar to aloe (Aloe vera) but is safer for dogs and cats. Aloe can cause vomiting and diarrhea.
