I love this plant, and I love the elaborate name~ which translates to Hercules Club. (It’s a reference to the classical Hercules, whose weapon of choice was supposedly a spiky club). It is known by a bunch of other names: Southern Prickly Ash, Pepperwood, Pepperbark, Tickletongue, or Toothache Tree. The leaves and bark contain a chemical that will numb your gums or teeth.
