Freesia is a beautiful flower with a light, sweet scent that can often fill a room. But if you have pets in your home, it's important to note that freesia can be toxic to them. While this fragrant flower is not as toxic as other plants, such as lilies and azaleas, ingesting any part of the plant can still cause an upset stomach or skin irritation. To keep your furry friends safe, make sure they don't have access to any freesia in your home or garden.
