46. Oklahoma – Water Hemlock (Cicuta maculata)
Water hemlock thrives in Oklahoma’s wetlands, streams, and damp fields. Its white flower clusters make it deceptively similar to edible plants, but its roots contain cicutoxin, a neurotoxin that causes violent seizures, respiratory failure, and death. Even minor ingestion is fatal. Livestock and children are particularly vulnerable. Historical poisonings highlight its lethality. Water hemlock’s subtle appearance and widespread growth make it one of Oklahoma’s deadliest plants, requiring extreme caution when encountered in the wild.
