With its rich colors and elegant images, the peony symbolizes peace and prosperity, and thus it is known as the “king of flowers” in China. The peony is cultivated and planted in many parts of China. For thousands of years, many poems and paintings have been created to praise the peony. During the Tang Dynasty, peonies were cultivated widely in royal gardens and were praised as “the national flower”, so they enjoyed great popularity. In the 10th century, the ancient city of Luoyang became the center for peony cultivation, and the position has been maintained till now. Now, thousands of tourists from home and abroad flock to Luoyang for the annual Peony Festival to enjoy the unique beauty of the peonies and explore the history of the ancient capital of nine dynasties.
