The Most Dangerous Plant In Each State

3. Florida – Manchineel Tree (Hippomane mancinella)

Often considered the most dangerous tree in North America, the manchineel grows along Florida’s coastal areas. Its small green fruits resemble apples and are extremely toxic. The sap causes severe skin burns, while inhaling smoke from burning wood can damage the eyes and lungs. Even standing beneath the tree during rain can cause blistering, as toxins leach from its leaves. The flowers are small and unassuming, offering no warning. Historically used for poison-tipped arrows, the manchineel remains a lethal presence disguised as a tropical beach tree.
