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 marginatum is naturalized along the central and southern coast of California, where it has been listed as a noxious weed by the California Department of Food and Agriculture. There are few recent collections. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
