The Most Dangerous Plant In Each State

28. Indiana – Water Hemlock (Cicuta douglasii)

Indiana’s water hemlock is notorious for its extreme toxicity. Found in wetlands, streams, and damp meadows, it produces small clusters of white flowers that can be easily mistaken for edible plants. The plant’s roots contain cicutoxin, a fast-acting neurotoxin that induces violent seizures, respiratory failure, and death. Even minor exposure can be fatal. It poses a significant risk to children, hikers, and livestock. Water hemlock is a prime example of a plant that looks harmless but carries one of the most dangerous toxic profiles in the region.
