Anything with the name “Nettle” gets my full attention. Having bumped into more than my share of Stinging Nettle (Urtica dioica), I am too aware of the result if one is careless around all those tiny irritating and sometime pain causing hairs. Unlike a true nettle, Horse Nettle (Solanum carolinense) aka Carolina Nightshade is not prized for any medicinal or food qualities despite being a relative of tomatoes and eggplant (and others in the Solanum or nightshade family). If it gets in the hay fed to horses and cattle they can be very unhappy with internal irritation from swallowing the tiny hairs that line the stems and leaves which you can see in the image. And they are also not a welcome find in most folks’ gardens.
