What is the most deadly plant on earth?

Deadliest plant on earth...Well that's alot of plants. My best guess would be the castor bean plant it produces castor beans which are used to make castor oil.

Then again there are alot of plants on earth and there may be some competition with the castor plant. Water Hemlock might give the castor bean some competition. bacause GOD made them!
