This Mu Dan Pi hails from Feng Huang (Phoenix) Mountain in An Hui province. This mountain is so-named because of a rock on the mountaintop that has an indentation that resembles one that would be made by a Phoenix claw. The story goes that the spot was a stopping place for Phoenixes. The beautiful tree peony flowers that grow on the mountain have become legendary and, since the Eastern Jin dynasty in the 4th century A.D., the plants have been considered to produce the finest grade of Mu Dan Pi. The fertile soil, plentiful rainfall and short frost season provide an ideal setting for the tree peony. See our Facebook page for pictures of Andy visiting the grower there. Mu Dan Pi is one of the four special herbs of An Hui province. The other three are Bai Shao (White Peony), Fu Ling (Poria) and Ju Hua (Chrysanthemum).
