DESCRIPTION:
Most of the common nightshades are annuals. The worst of the nightshades are black nightshade (S. nigrum ) and hairy nightshade (S. sarrachoides). First true leaves of hairy nightshade have wavy edges and prominent veins. The leaves have numerous fine, short hairs, especially along the underside of the main vein. Berries are green or yellowish brown when mature, never black. The calyx covers the entire upper surface of the fruit. The pedicels, like stems and leaves, are usually hairy. Mature plants reach about 2 feet (60 cm) in height.
