Sunflowers, marigolds, snapdragons and roses are all pet-friendly cut flowers. It is always good to check that your plant is safe for your pet. You may not realise that lilies, chrysanthemums, carnations, and tulips are all toxic to pets. Although the RSPCA believes most animals rarely ingest enough of the plant to react because of the unpleasant taste. It is still a good idea to place bouquets containing these flowers just out of the reach of your pets. For the complete list of toxic flowers and plants, please visit the RSPCA.
