Black Night Shade Solanum nigrum L An Updated Overview

Abstract: Solanum nigrum L. (Family Solanaceae; English name: Black night shade) is one of the largest and most variable species groups of the genus. Species belonging to this section are distributed from temperate to tropical regions, and from sea level to altitudes over 3500 metres. Though this species group is often referred to as Solanum nigrum complex, the section is composed of a large number of morpho-genetically distinct taxa, which show their greatest diversity and concentration in the New World tropics, particularly in South America. Solanum nigrum itself is a predominantly Eurasian species, which does not occur naturally in South America. In most parts of the world, particularly in Europe and North America, these species are considered to be troublesome weeds of agriculture, but in many developing countries they constitute a minor food crop, with the shoots and berries not only being used as vegetables and fruits, but also for various medicinal and local uses.
