Redcurrant in Europe, Asia and North America, also with edible fruit. These include "Ribes spicatum" (northern Europe and northern Asia), "Ribes alpinum" (northern Europe), "R. schlechtendalii" (northeast Europe), "R. multiflorum" (southeast Europe), "R. petraeum" (southwest Europe) and "R. triste" (North America; Newfoundland to Alaska and southward in mountains). While "Ribes rubrum" and "R. nigrum" are native to northern and eastern Europe, large berried cultivars of the redcurrant were first produced in Belgium and northern France in the 17th century. In modern times, numerous cultivars have been selected; some of these have escaped gardens and can be found in the wild across

Some of the uses ascribed to "S. nigrum" in literature may actually apply to other black nightshade species within the same species complex, and proper species identification is essential for food and medicinal uses (See "Taxonomy" section). "S. nigrum" has been widely used as a
