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.

Solanum jamaicense is thought to have been spread to Florida by birds that eat the bright red berries. It was first seen in the state in 1930 and, although locally invasive in hammocks of central Florida, has not become a widespread pest.
