Solanum chenopodioides has been introduced sporadically and is occasionally adventive in North America. It is distinctive in having the fruiting peduncles strongly reflexed downward, but is otherwise difficult to distinguish from S. pseudogracile, with which it may be conspecific. The illegitimate superfluous name Solanum gracile Dunal has often been used for S. chenopodioides (for example, J. K. Small 1913; A. E. Radford et al. 1968). W. G. D’Arcy (1974) included S. gracile (and its replacement name S. ottonis) in the synonymy of S. nigrescens but the taxa are distinct.

Solanum diphyllum is often cultivated for its brightly colored fruits and can escape from cultivation in tropical and subtropical areas. It occurs sporadically and does not appear to be common, but in other areas where it has escaped it has become naturalized (Asia; S. Knapp 2002b).
