Yes. The ASPCA specifically classifies Centaurea cyanus, also called cornflower or bachelor’s button, as non-toxic to dogs and cats. Toxicity is therefore marked FALSE and pet friendly is marked TRUE. This value concerns the plant itself. Even a non-toxic plant may cause digestive discomfort when an animal consumes a large amount. Fertilizers, pesticides, fungicides, and growing media carry their own risks. Keep packets, seeds, and recently treated plants out of reach. If substantial consumption or unusual symptoms occur, contact a veterinarian and provide the name Centaurea cyanus along with the products applied during cultivation. A pet-friendly plant should not be used as routine pet food, and all packet precautions still apply.
