Datura

Deceitful Charms

Origin: Datura, while it may charm you with its beautiful appearance, is extremely poisonous if ingested. The flowers, also known as "devil's trumpets," are said to have been used in early European witchcraft as an ingredient in the ointment that allowed witches to fly on their broomsticks.
