African Daisy is a common name that refers to several species within the genera Osteospermum and Dimorphotheca, both members of the vast Asteraceae (or Compositae) family. These popular ornamental plants are prized for their vibrant, daisy-like flowers that bloom in a spectrum of colors, often with striking contrasting centers. It is crucial to distinguish these plants from others that may share the "daisy" common name, as toxicity can vary significantly between different botanical families. The African Daisies discussed here are typically non-native, warm-weather perennials often treated as annuals in cooler USDA hardiness zones.
According to the American Society for the Prevention of Cruelty to Animals (ASPCA), which maintains a comprehensive toxic plant database, plants in the Osteospermum genus are classified as non-toxic to both dogs and cats. Similarly, plants in the closely related Dimorphotheca genus are also generally considered non-toxic. Unlike some members of the Asteraceae family that contain pyrethrins or sesquiterpene lactones which can cause gastrointestinal upset, African Daisies are not known to contain these irritating compounds in significant amounts. They lack the potent toxins found in seriously poisonous plants such as lilies (which are highly toxic to cats) or sago palms.
While African Daisies are not chemically poisonous, they are not intended for consumption. The primary risk associated with a dog or cat ingesting this plant is mild physical and gastrointestinal irritation. The plant's fibrous leaves and stems are difficult to digest. If a pet consumes a large amount of the plant material, it could potentially lead to mechanical irritation of the mouth, throat, and digestive tract. This might manifest as symptoms like mild drooling, vomiting, or diarrhea as the animal's body attempts to expel the unfamiliar and indigestible matter. The risk is similar to that of eating any non-food plant, where the physical properties of the plant, rather than its chemistry, cause the discomfort.
For pet owners who wish to cultivate African Daisies, the overall risk is low. However, it is always prudent to practice preventative measures. Consider placing planters in areas that are less accessible to curious pets, such as on high shelves or in rooms that can be gated off. Providing pets with their own safe, edible grass can help deter them from nibbling on ornamental plants. Always monitor your pets when they are in the garden, especially when introducing new plants to the environment. If you suspect your pet has a tendency to chew on plants, erring on the side of caution is recommended, even with plants deemed non-toxic.
