White Nightshade (Solanum nodiflorum, one of numerous synonyms of Solanum americanum) is a common weed in the Solanaceae family. Known by many common names, including American Black Nightshade, Smallflower Nightshade, Common Nightshade, Garden Nightshade and Glossy Nightshade, it is poisonous, especially the leaves and the green fruit. Native in North America, Mexico, Central and South America, it has spread to tropical and temperate regions throughout the world. It is a short-lived, rough-stemmed herbaceous plant or small shrub, growing in an erect manner to four feet or more in height. It is known to bloom throughout the year depending on conditions. It has small star-shaped flowers that grow in small clusters at the forks of upper leaves, each flower with five white petals and five yellow stamens. The flowers are followed by green, round berries that ripen to become shiny and black. Its leaves are (mostly) hairless, either smooth-edged or edged with large, rounded teeth.
