Carolina horsenettle
Solanum carolinense, the Carolina horsenettle, is not a true nettle, but a member of the Solanaceae, or nightshade family. It is a perennial herbaceous plant, native to the southeastern United States, though its range has expanded throughout much of temperate North America. The plant is considered to be invasive in parts of Europe, Asia, Africa and Australia. The stem and undersides of larger leaf veins are covered with prickles.
