Danjing Mountain in Pengzhou began to grow peony in the Tang Dynasty. In 1985, peony was selected as the city flower of Peng zhou City. The annual peony fairs held in April have helped to attract a continuous flow of tourists. Danjing Mountain, 50 km away from Chengdu, is the largest peony growing center in west China. Danjing Mountain peony shares the same reputation with Luoyang peony in Henan Province and Heze peony in Shandong Province. The Danjing Mountain Peony Garden is home to over 250 kinds of peony. Eight peony samples, Chinese herbaceous peony garden, crape myrtle garden and yellow azalea garden, which cover a total area of some 6.6 hectares have been open to the public.
