Is Asparagus Fern Toxic to Cats and Dogs?
The Asparagus Fern is toxic to both cats and dogs. This popular houseplant can cause problems if a pet repeatedly touches it or eats the plant’s berries. Pet owners should understand the risks associated with having this plant in their home.
Asparagus Fern goes by many other common names, including Emerald Feather, Emerald Fern, Sprengeri Fern, Plumosa Fern, and Lace Fern. All refer to the same plant, Asparagus densiflorus cv sprengeri, which is a member of the Liliaceae family. Knowing these names can help you identify it correctly and keep your pets safe.

What the ASPCA says about Asparagus Fern
The American Society for the Prevention of Cruelty to Animals (ASPCA) lists Asparagus Fern as toxic to both cats and dogs. The plant’s effects on pets depend on the type of exposure. The ASPCA database notes two primary concerns for pets who come into contact with this plant.
First, repeated dermal exposure, which means rubbing against the plant’s foliage multiple times, can lead to allergic dermatitis. This is an uncomfortable skin irritation or rash. Second, the ingestion of the plant’s berries is a concern. If a dog or cat eats the berries, it could result in gastric upset. The specific signs of this stomach and intestinal distress include vomiting, abdominal pain, or diarrhea.
What this means for a home with pets
Understanding the specific risks helps pet owners manage a home with an Asparagus Fern. The main issues are skin irritation from repeated contact with the plant and stomach upset from the berries. The berries present a clear risk of gastrointestinal problems if eaten.
Cats who like to brush against or bat at houseplants might be more prone to developing skin irritation over time. Dogs, especially curious puppies, might be more likely to chew on and swallow the berries. Because every pet’s reaction can be different, it is always safest to prevent access entirely. The size of the pet and the amount of plant material consumed can influence the severity of the symptoms.
How to keep pets and this plant separate
The most effective way to prevent a negative reaction is to ensure your cat or dog cannot get to the plant. Place Asparagus Ferns on very high shelves, in hanging baskets well out of reach, or in a room that your pets cannot access. Constant supervision is key when pets are around any potentially toxic plant.
Regularly inspect the plant and the area around it. Clean up any fallen leaves or berries immediately to remove the temptation for a curious pet to taste them. If you have a dog that likes to dig, be mindful of outdoor plantings. Providing safe, pet-friendly toys and activities can also help redirect a pet’s attention away from chewing on household plants.
When to call your vet
If your pet chewed or ate part of this plant, call your veterinarian or an animal poison control line. Note which plant and which part, how much may be gone and when, and take a photo or a piece of the plant with you.
If you suspect your pet has eaten any part of an Asparagus Fern, especially the berries, or if you notice signs of skin irritation or gastric upset, contact your veterinarian or a pet poison control hotline right away. One option is the ASPCA Animal Poison Control Center at (888) 426-4435, though a consultation fee may apply. Be prepared to tell the veterinary professional what your pet was exposed to, how much you think they consumed, and when it happened.
