Common NZ Garden Plants That Are Toxic to Pets

New Zealand gardens are beautiful, but many common plants can be toxic to dogs and cats. Whether you are a pet owner tending your garden or a pet sitter looking after someone else’s home, it pays to know what to watch out for.

Lily Species

Many lily species are extremely toxic to cats. Even small amounts of pollen or water from a vase can cause kidney failure. Common culprits include Easter lilies, tiger lilies, and day lilies. If you have cats, remove all lilies from your home and garden.

Cycads (Sago Palms)

Popular in NZ landscaping, cycads are highly toxic to dogs. All parts of the plant are dangerous, but the seeds are the most toxic. Ingestion can cause liver failure and can be fatal.

Rhubarb Leaves

Common in Kiwi vege gardens, rhubarb leaves contain oxalic acid which can cause kidney problems in pets. The stalks are safe for humans but keep pets away from the leaves.

Agapanthus

Found in gardens across NZ, agapanthus can cause nausea, vomiting, and diarrhoea if ingested by pets. While not usually fatal, it can make your pet quite unwell.

Karaka Berries

Native to NZ, karaka trees produce orange berries that are toxic to dogs. The kernels contain karakin, which can cause paralysis and even death. Be cautious during autumn when berries fall.

What to Do If Your Pet Eats a Toxic Plant

Contact your vet immediately or call the NZ National Poisons Centre on 0800 764 766. Take a sample of the plant with you if possible. Do not try to make your pet vomit unless specifically advised by a vet.
