Where is the most famous peony flower? Where was peony first planted?

Heze peony is the best in the world, and the peony in the world comes out of Heze. Heze, Shandong Province, known as Cao Zhou in ancient times, is a world-famous hometown of peony. Heze is famous for its national flower peony. From 65438 to 0999, the planting area of peony in the city has reached 50 thousand mu, with a total output value of more than 800 million yuan and foreign exchange earned by export of more than 30 million US dollars. Peony-based flower industry has become a pillar industry in Heze.

Peony planting in Heze began in the Southern Song Dynasty and flourished in the Ming and Qing Dynasties. After liberation, it developed rapidly, especially after the Third Plenary Session of the Eleventh Central Committee. Heze peony flower is large, colorful, beautiful and fragrant, which is the top grade of ornamental peony. From the appearance, it has three types (single petal, double petal and thousand petals), six types (sunflower, lotus, rose, hemisphere, crown and hydrangea) and nine color systems (red, white, pink, yellow, purple, blue, black, green and multicolor), among which black peony and green peony are the rarest. However, Heze people who have been closed for a long time have always regarded peony as medicinal materials and ornamental flowers, and have not promoted peony as a commodity, let alone developed peony as an industry. From 65438 to 0992, with the approval of the State Council, Heze held the first International Peony Fair. Tens of thousands of Chinese and foreign guests witnessed Heze's "Peony Blossom" and discussed economic and trade cooperation. The 9th Heze International Peony Fair has been held, and the export turnover alone reached more than US$ 654.38 billion. At present, Heze Peony has accounted for 85% of domestic sales. Heze peony strutted towards the international market.

Holding a flower show broadens Heze people's horizons and develops the peony-based flower industry into a pillar industry. They invited experts and professors to redesign the peony garden according to the principle of combining arbor, shrub and grass and paying attention to the style of external garden construction. With the Peony Office as the center, the square garden is planned to be a peony industrial zone of 35 square kilometers. More than 10 townships and villages plant peony in a large area, with an annual increase of 1 10,000 mu. Peony resource garden and peony gene bank have also been established rapidly. At the same time, cooperate with China Academy of Agricultural Sciences, Beijing Forestry University and other universities and scientific research units to increase the scientific research and development of peony. Major breakthroughs have been made in scientific research topics such as peony flower forcing, fresh cut flowers, variety breeding, soilless culture and tissue culture. It has become a reality that peony blooms in four seasons, and the technology of bud grafting and rapid propagation has been popularized. Heze Peony with high-tech content won two world awards and 79 gold, silver and bronze awards in one fell swoop at the 99 Kunming World Horticultural Exposition in China, accounting for 73.2% of the total number of awards, which established Heze Peony's world dominance. Peony-based flowers have become the most dynamic economic growth point in Heze.
