The Datura genus is famed for its striking yet perilous plants, often called Devil’s Trumpet or Thorn Apple. Despite their alluring appearance, these plants are extremely toxic and pose a severe threat to human and animal health. Below, we explore the Datura genus, its common species, and the dangers associated with these poisonous plants.
What Is the Datura Genus?
