Discussion | Solanum torvum is listed by the United States federal government and several states as a noxious weed. It is occasional to rare in peninsular Florida and could possibly become invasive elsewhere in subtropical climates. The green fruits are used in Asian and West Indian cuisine, often as an addition to soups and curries. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Solanum deflexum occurs sporadically in southeastern Arizona (Cochise, Pima, Pinal, and Santa Cruz counties). It is unique in its fruits with explosive dehiscence. As the berries mature, they build up turgor pressure until they burst, propelling seeds up to several feet from the parent plant. Plants of S. deflexum were often identified as S. adscendens Sendtner (M. Nee 1989), a distinct species found only in South America (S. Stern et al. 2013).
