Did you know

  • Despite the name, horse nettle is neither a horse plant nor a nettle — it is a nightshade relative of tomatoes.
  • The yellow berries resemble tiny tomatoes but are toxic to humans, containing the alkaloid solanine.
  • Its stems and leaf veins are armed with sharp, star-shaped spines that easily pierce gloves.
  • Horse nettle has roots that can extend 3 m deep, making it nearly impossible to eradicate by pulling.
  • Some Native American tribes used very small, controlled doses of the root to treat sore throats.
