Deadly Nightshade or Bittersweet Nightshade Solanum dulcamara

Deadly Nightshade, while not actually seriously deadly, can cause poisoning (though not usually fatal) if eaten in large quantities. This vine is an import from England, but it is now widespread and common on the American landscape. The vine itself is attractive, and the berries, which start out green and turn bright red later in the summer are extremely eye-catching, as shown in the picture here. The berries replace this vine's distinctive purple and yellow flowers, which are very delicate, rich in color, and spectacularly lovely in quantity. Because it has both berries and flowers almost all summer long, this plant is easy for almost anyone to recognize.
