Human Potential

Pampas grass is known by the botanical name Cortaderia selloana. According to the University of Arkansas, Division of Agriculture, pampas grass is not known to cause symptoms of plant poisoning if ingested by humans. However, any plant can cause allergic reactions or other adverse effects if ingested. Choking is a concern with plant ingestion, especially in children.

Animal Potential

The American Society for the Prevention of Cruelty to Animals states that pampas grass is non-toxic to dogs, cats and horses. Ingesting any type of plant material, however, can cause uncomfortable gastrointestinal symptoms such as diarrhoea, depression and vomiting in animals.


Pampas grass ingestion that causes severe or long-lasting symptoms in humans or animals requires an evaluation by a medical professional. Bring a sample of the plant with you to the doctor or veterinarian to ensure proper plant identification.
