Paeonia suffruticosa

Paeonia suffruticosa is a name used for a group of culture varieties of tree peonies that are the result of hybridisation with species exclusively belonging to the subsection Vaginatae. The common name used in China is mǔdān (Chinese: 牡丹). Plants belonging to this group have been cultivated for millennia in China, initially only as a source of traditional Chinese medicine particularly the skin of its roots (牡丹皮; mǔdān pí). Already early on the plant was also cultivated for its ornamental value, and it is highly revered in Chinese culture.
