These trumpet-shaped flowers are quite beautiful to look at. They have a unique shape and color that’s symbolic of springtime. Unfortunately, though, they don’t represent any part of springtime if you ingest them. All of the parts of the flower are poisonous, including the stem, leaves, and pollen. They’re especially toxic for cats, in that even if they ingest a small amount, they may suffer from vomiting, increased thirst, and kidney failure (Plantura).
