  Hi davih158,
  I could say some tropical poisonous plant that none of us have even heard of, but the most deadly plant to humans is probably tobacco. The number of deaths caused by smoking the tobacco plant is huge and it is also highly addictive. So, the most deadly plant in the world is available to buy in the corner shop! A scary thought!!
