Below is a list of 21 trees whose leaves are being used in Ganesh Chaturthi Puja.
In Hinduism, flowers and leaves are given utmost importance while worshipping Hindu Gods and Goddesses. All Gods and Goddesses have their own favorite list of flowers and leaves.
While worshipping Gods and Goddesses, devotees choose only those flowers and leaves which are favorite of the deity. Some flowers and leaves are prohibited for some of the deities and should not be offered to them.
21 different types of leaves are suggested for Ganesha Chaturthi Puja and popularly known as Patris Puja or Patra Puja. As it is not practical to have all of them during the Puja time, devotees can include some of them in Puja Samagari.
Due to one legend in Ganesha Purana which talks about Tulasi and Lord Ganesha cursing each other, Tulasi leaves are not offered to Lord Ganesha. However as an exception Tulasi leaves are offered to Lord Ganesha during Ganesha Chaturthi Puja which is also known as Vinayaka Chaturthi Puja.
