Jamestown weed is often more commonly known as "jimsonweed" or simply "jimpson". It is a poisonous annual
plant (Datura stramonium
) in the nightshade
). It has stinky leaves and white trumpet-shaped blooms and is the source of many useful alkaloid
s, including atropine
Reputedly, the early settlers in Jamestown, Virginia discovered the toxic effects of the plant when a cook mistakenly collected several of them to make a side dish of greens to a meal.
