Beautiful plants can be dangerous to both animals and humans. You may be surprised to find out that the United States has more than a few deadly flowers.
These colorful wonders of nature are incredibly beautiful, but did you know some of them can actually make you sick? Some of these deadly flowers are hard to find, while others may be scattered throughout your town. It’s especially important to know which plants to watch out for if you have pets, livestock, or young children who may not know better than to ingest a wild plant.
With poppy seeds commonly found in baked goods, salad dressings, and more, you might be surprised to find out that the poppy plant is actually poisonous. Found across the West Coast, poppy flowers have alkaloids in them which make them poisonous to people and animals. Poppy leaves, the stem, flower and seeds contain opiates including morphine and codeine.
In small amounts, poppy seeds are completely safe. However, the poppy plant can be harmful if ingested raw and unripened. Side effects of consumption typically begin with euphoria or relaxation. This then leads to lack of appetite, muscle twitching, difficulty walking, and slow heart rate. If you, your children, or pets eat any part of a poppy flower and begin showing these symptoms, seek medical attention immediately, as ingestion can lead to death.
2. Water Hemlock
Water hemlock is known as one of the deadliest flowers in the United States, and it’s found all across North America and Europe. It thrives in moist areas like meadows, marshes, and ponds.

Water hemlock is dangerous to both people and animals as it causes vomiting and violent convulsions. Even a tiny piece can kill a large animal.
Monkshood, also known as Wolfsbane, is found all along the western half of the United States. It is also extremely dangerous. The sap from monkshood can cause both heart and respiratory failure.

Oleander is found along the East Coast as well as in California and Texas. While it’s native to (sub)tropical areas, this plant is very hardy and easy to take care of. It’s commonly used as a freeway divider because it grows quickly into tall shrubs. Consuming oleander can lead to blurred vision, vomiting, diarrhea, stomach pain, confusion, headache, and even serious heart problems. Just a small amount of this deadly flower can be lethal.
