The Most Dangerous Plant In Each State

31. Hawaii – Cerbera odollam (Suicide Tree)

Hawaii’s warm, coastal environments support the rare but deadly Cerbera odollam, known as the “suicide tree.” Its cream-colored flowers and mango-like fruit are deceptively beautiful. Every part contains cerberin, a potent cardiac toxin that can induce nausea, irregular heartbeat, seizures, and death. Historically, it has been used for untraceable poisonings in Southeast Asia. Even minimal exposure, such as handling leaves or consuming the fruit, can be fatal. Its presence in ornamental plantings and coastal areas makes it a hidden danger, reminding visitors that nature’s beauty can sometimes mask lethal threats.
