Jimsonweed (Datura stramonium L.)
All parts of the Jimsonweed are poisonous, but because of its strong odor and unpleasant taste, animals rarely eat enough of the green plant to be poisoned. Poisoning in animals occurs primarily when hungry animals are turned into a Jimsonweed-infested area where better forage is absent. Most cases of animal poisoning result from a quantity of the dried plant being fed in hay, while poisoning in chickens is due to eating of the seeds. Occasionally Jimsonweeds are accidentally included when the silo is filled. When the silage is fed to the animals poisoning occurs.
Jimsonweed is also known as Jamestown weed because of the mass poisoning of soldiers in Jamestown, Virginia in 1676. Jimsonweed poisoning is more common among humans than in animals.
