Extra notes and interesting information:

The seeds within the berries are highly toxic.  Pokeweek poisonings were common in North America during the 19th century.

 Poke berries make a beautiful short-term purple dye.

 Propagate from seed ; winter sow in vented containers, coldframe or unheated greenhouse.

 May be a noxious weed or invasive.

 A patent has been filed to use poke toxins to control zebra mussels.

 There is evidence of some anti-cancer effects of the plant.
