- Water Hemlock (Cicuta spp.)
Water hemlock is considered one of the most poisonous plants in North America. It contains cicutoxin, which affects the nervous system and can cause violent convulsions, nausea, and death within a few hours of ingestion.
- Manchineel Tree (Hippomane mancinella)
The manchineel tree is native to the Caribbean and Florida, and it has earned the nickname “tree of death” for a good reason. All parts of the tree, including the sap and fruit, are highly toxic and can cause severe skin irritation, blisters, and internal organ damage if ingested.
- Giant Hogweed (Heracleum mantegazzianum)
Giant Hogweed may look impressive with its towering height and large white flowers, but it is a dangerous plant. Its sap contains chemicals that cause severe skin burns and blisters upon contact with sunlight, a condition known as phytophotodermatitis.
