Solanum sisymbriifolium
Solanum sisymbriifolium is native to southern South America, but is now found worldwide.
It grows in dry areas and subtropical forests and savannas, and is very common in both the wet and dry Chaco biome.
In the United States it is found in all the southern states and in Canada near the Great Lakes. It can grow anywhere where it is not completely killed by frost before setting fruit and scattering its seed.
