The 'Hercules Club' is a fragrant tree characterized by its rounded canopy. This species is indigenous to the coastal plains of North Carolina, thriving in the light, sandy soils found in maritime forests, dunes, riverbanks, and on island bluffs. Notably, every part of the tree produces a numbing sensation when chewed, which is why it is often referred to as the 'Toothache Tree.'
