context_page_description: 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 that has spread widely throughout much of temperate North America. It has also been found in parts of Europe, Asia, and Australia. The stem and undersides of larger leaf veins are covered with spines.
  "Horsenettle" is also written "horse nettle" or "horse-nettle", though USDA publications usually use the one-word form. Though there are other horsenettle nightshades, S. carolinense is the species most commonly called "the horsenettle". Other common names include radical weed, sand brier or briar, bull nettle, tread-softly, Solanum mammosum, devil's tomato and wild tomato.
context_section_description: Carolina horsenettle is considered a noxious weed in several US states. It can spread vegetatively by underground rhizomes as well as by seed. It is resistant to many postemergent herbicides and somewhat resistant to broad-spectrum herbicides such as glyphosate and 2,4-D. In fact, herbicide use often selects for horsenettle by removing competing weeds. It is an especially despised weed by gardeners who hand-weed, as the spines tend to penetrate the skin and then break off when the plant is grasped. The deep root also makes it difficult to remove.
