I agree, Pokeweed and be aware if you have small children or pets, the plant is toxic.
From Wikipedia:
~ Toxicity, poisoning, and mortality: The information with regard to the overall and significant toxicity of this plant and the risks to human and mammalian health it poses is consistent and pervasive. In summary, with regard to distribution through the plant: the poisonous principles are found in highest concentrations in the rootstock, then in leaves, and stems, and then in the ripe fruit, the plant generally gets more toxic with maturity, with the exception of the berries (which have significant toxicity even while green).
With regard to human and animal (pet and livestock) toxicity, the Ohio Agricultural Research and Development Center (OARDC) staff scientists note that all parts of common pokeweed are toxic... Roots are the most poisonous, leaves and stems are intermediate in toxicity (toxicity increases with maturity), and berries are the least toxic."
With regard to human poisoning they note: "Children are most frequently poisoned by eating raw berries. Infants are especially sensitive and have died from eating only a few raw berries. Adults have been poisoned, sometimes fatally, by eating improperly prepared leaves and shoots, especially if part of the root is harvested with the shoot, and by mistaking the root for an edible tuber. Research with humans has also shown that common pokeweed can cause mutations (possibly leading to cancer) and birth defects. Since the juice of pokeweed can be absorbed through the skin, contact of plant parts with bare skin should be avoided."
As summarized by Michael D.K. Owen, for the Iowa State University Extension Service: "Most authorities regard the plant as poisonous... Humans have been poisoned by eating parts of the root, which is the most poisonous part of the plant. Children are often attracted by the bright crimson juice of the berries and can be poisoned by eating the berries...
If death occurs, it is usually due to paralysis of the respiratory organs... Because of the danger of human poisoning, pokeweed should be eradicated when discovered. This is especially true if the plants are in hedges, gardens, and other areas adjacent to a home where children may be attracted by clusters of berries."
A further well-referenced web reference on the toxicity states that pokeweed is to be avoided during pregnancy and notes that "children consum[ing] even one berry" require that "emergency poison treatment... be instituted"; in terms of general exposure, it notes "plant sap can cause dermatitis in sensitive people" and that "it is strongly recommended that the people wear gloves when handling the plant."
Regarding pet, livestock, and other mammailian poisoning, Owen notes that "birds are apparently immune to this poison" and that "animals usually do not eat the plant because of its bitter taste." The OARDC scientists echo the lack of animal palatability, and note that "most animals avoid eating it unless little else is available, or if it is in contaminated hay. Horses, sheep and cattle have been poisoned by eating fresh leaves or green fodder, and pigs have been poisoned by eating the roots."
