Is this plant poisonous?
We are not medical experts nor certified to tell you a plant is or is not poisonous. What I can tell you is that "Joe Pye Weed" is a common name used for multiple varieties of the Eupatorium genus. "Pokeweed" is defined by Webster's dictionary as a member of the Phytolacca genus. The same common name is often used for more than one plant or different common names can refer to the same plant. Common sense tells you that you never should eat or drink any substance which you cannot accurately and positively identify.
