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
Solanum nigrum varieties and forms described. The recognized subspecies are: 1. "S. nigrum" L. subsp. "nigrum" — glabrous to slightly hairy with appressed non-glandular hairs 2. "S. nigrum" L. subsp. "schultesii" (Opiz) Wessley — densely hairy with patent, glandular hairs The Solanum nigrum" complex — also known as Solanum" L. section "Solanum" — is the group of black nightshade species characterized by their lack of prickles and stellate hairs, their white flowers, and their green or black fruits arranged in an umbelliform fashion. The "Solanum" species in this group can be taxonomically confused, more so by intermediate forms and hybridization between the
