Datura flowers, commonly known as jimson weed, devil's trumpet, devil's weed, thorn apple, are used to adorn Shivling in many Shiva temples. Datura garlands are offered to Shiva and are available outside many Shiva temples. Legend has it that the Dhatura flower appeared from the chest of Shiva. This is mentioned in the Vamana Purana.
Sadhus who are worshippers of Shiva smoke the leaves and seeds of Datura plant. This is a poisonous plant and is not used by common people.
The plant along with its leaves, flowers and fruits are offered on Mahashivaratri night. The flower is used to worship of the Pradosh day – 13th day of a lunar fortnight.
