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.
