Purple fountain grass, sometimes called red fountain grass, is known by the scientific name Pennisetum setaceum 'Rubrum'. A low-maintenance plant with few requirements, the striking foliage is a draw for many gardeners. Dogs occasionally graze on grass to calm their stomachs and gain additional nutrients, making it imperative for dog owners to maintain pet-safe plants.
Purple fountain grass is tinged reddish, copper or purple. Leaves grow 3 to 4 feet in length. The plant produces foot-long feathery flower stalks from early summer to mid fall.
The Pawprints and Purrs website identifies purple fountain grass as nontoxic to pets. The American Society for the Prevention of Cruelty to Animals does not list purple fountain grass among the plants hazardous to dogs.
While purple fountain grass doesn't contain any known toxins, the addition of strange roughage to your dog's stomach can cause irritation, including vomiting and diarrhea. Additionally, some dogs develop allergies to certain plants.
If your dog has a persistent upset stomach or can't keep fluid or food down after eating purple fountain grass, speak to a veterinary medical professional.
