Tree peonies are deciduous shrubs belonging to genus Paeonia L., section Moutan DC., family Paeoniaceae Rudolphi. They are important ornamental and resource plants, having been cultivated in China for more than 1500 years; currently there are ≈1500 cultivars. Tree peony is one of the famous traditional flowers in China and is also well-known in the world. Tree peony flower is regarded as possessing graceful bearing of the king of flowers attributable to its elegance, various flower forms, the poised and dignified carriage, and great charm, which imply riches, honor, and good luck. They or their decorative patterns can be seen in the public parks, gardens of the imperial palaces, on folk arts, crafts, pottery, porcelain, and carvings. Tree peony is praised or cited in poems, songs, legends, and mythology. There are close relationships between tree peony and Chinese culture. Chinese flower farmers have developed consummate skills in cultivation and breeding of tree peony cultivars in the past more than 1500 years.
Because it is well-known worldwide, Heze city (Shandong Province) is one of the important production and commercial centers of tree peonies in China. To promote utilization of Chinese tree peony cultivar resources, gardening of cities and towns as well as sustainable development of the tree peony industry, as part of the work of a project for conducting an assessment of germplasm resources of Chinese tree peony cultivars, we report an outstanding Chinese tree peony cultivar with unique characteristics of possessing side flowers and bicolored floral discs.
