phytolacca

Phytolacca americana, also known as American pokeweed, pokeweed, poke sallet, pokeberry, dragonberries, pigeonberry weed, and inkberry, is a poisonous, herbaceous perennial plant in the pokeweed family Phytolaccaceae. This pokeweed grows 1 to 3 metres. It has simple leaves on green to red or purplish stems and a large white taproot. The flowers are green to white, followed by berries which ripen through red to purple to almost black which are a food source for songbirds such as gray catbird, northern mockingbird, northern cardinal, and brown thrasher, as well as other birds and some small non-avian animals. — Wikipedia
