Peaches of Immortality

"In China, the peach was said to be consumed by the immortals due to its mystic virtue of conferring longevity on all who ate them. The divinity Yu Huang, also called the Jade Emperor, and his mother called Xi Wangmu also known as Queen Mother of the West, ensured the gods' everlasting existence by feeding them the peaches of immortality. The immortals residing in the palace of Xi Wangmu were said to celebrate an extravagant banquet called the Pantao Hui or "The Feast of Peaches". The immortals waited six thousand years before gathering for this magnificent feast; the peach tree put forth leaves once every thousand years and it required another three thousand years for the fruit to ripen. Ivory statues depicting Xi Wangmu's attendants often held three peaches. The peach often plays an important part in Chinese tradition and is symbolic of long life. One example is in the peach-gathering story of Zhang Daoling, who many say is the true founder of Taoism. Elder Zhang Guo, one of the Chinese Eight Immortals, is often depicted carrying a Peach of Immortality."  -  Wikipedia
