Luoyang peony has been mainly ornamental since ancient times, influenced by imperial capital culture and promoted by aristocratic culture. Therefore, there are many kinds of peony in Luoyang, including single petal, heavy color, light color, double color and color change. Coupled with the strong local peony culture in Luoyang and the accumulation of tourist cities that have been operating for many years, in the flower viewing season in April every year, Ouyang Xiu's poems describe that "the beautiful scenery of Luoyang is always remembered, and the nightingale banquet seems to leave people." The grand occasion of flower viewing continues to this day.
