nightshade,common name for the Solanaceae, a family of herbs, shrubs, and a few trees of warm regions, chiefly tropical America. Many are climbing or creeping types, and rank-smelling foliage is typical of many species. The odor is due to the presence of various alkaloids (including scopolaminescopolamine

The black nightshade was named for the dull black color of its berries, unusual for the genus; it is native to Europe but naturalized throughout the United States, where it is now one of the most common species of Solanum found growing wild. Because its leaves may be poisonous, it is sometimes called deadly nightshade, properly the name for the belladonna, which is not found wild in America. Nightshades are classified in the division MagnoliophytaMagnoliophyta
