It is the tree species behind the immortal that provided shade from the sun and rain when he attained enlightenment. It blooms and bears fruit. The flowers are called Udumbara flowers or Udumbara flowers, referred to as Udumbara flowers, and are also called "Lingrui flowers" in scriptures. Udumbara is Sanskrit, which means spiritual flower, empty flower, and empty flower. Volume 8 of "Jiuzhou Zhi" states, "The Udumbara flower is felt by auspicious spirits. It is a small flower that does not exist in the world. If the Tathagata is reborn and an immortal appears in the world, he will feel the appearance of this flower due to the power of great merit."
