The Most Dangerous Plant In Each State

45. Kansas – Poison Ivy (Toxicodendron radicans)

Poison ivy grows widely across Kansas forests, fields, and suburban areas. Its green leaves turn red in fall, and clusters of white berries attract attention. Contact with urushiol oil causes severe skin rashes, blistering, and, in rare cases, systemic reactions. While rarely fatal, infections from scratching can be serious. The plant spreads easily and can transfer oil to others, making it highly contagious. Despite being non-lethal compared to some other plants, poison ivy remains one of the most notorious and irritating plants in the state.
