POKEBERRY, POKEWEED (from the American-Indian pocan, applied to any plant yielding a red or yellow dye), in botany, the popular name of Phylolacca decandra, a strong-smelling perennial herb, a native of North America, with ovate-lanceolate sharp-pointed leaves, racemes of small greenish-white flowers and flattish berries nearly 12 in. in diameter, which contain a crimson juice. The young asparagus-like shoots are sometimes used as a pot-herb, but the roots are poisonous. The plant is often cultivated in Europe, and has become naturalized in the Mediterranean region.
