Rhododendron—The prettiest of the most poisonous yard plants

While this strikingly bright flower, common in Asia and Appalachia in the United States, may look beautiful, especially when hanging over a picket fence, it is in fact, highly toxic. Some species of rhododendron are poisonous to animals due to a toxin called Grayanotoxin in their pollen and nectar. For humans, ingesting a flower, stem or leaf can lead to abdominal pain, difficulty breathing, paralysis and even coma.
