I think that pokeweed, the Phytolaccaceae family, is endemic to the Americas and Africa. The most prolific here in the States are those beauties pictured above, Phytolacca americana. It's actually a highly medicinal plant, though because of the toxicity, as @cognoscere noted (kill you dead toxicity), it's recommended that you use this only under the guidance of an herbalist who is very experienced with it. And do your research of course... Excellent photos! Anyone who didn't know how to recognize this plant certainly will after seeing your post, @cognoscere. Thanks for sharing!
