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 pseudogracile is very similar to and perhaps not distinct from S. chenopodioides. It is ecologically distinctive, occurring in sand dunes and salt marshes of the Atlantic and eastern Gulf Coastal Plain and inland in some parts of Florida and Georgia.
