The fibrous roots mainly grow from the roots, and their main function is to absorb water and nutrients.

The front end of the leaves is sharp. The edges of the leaves are dense with white fine teeth. The color of the leaves is yellow-green, dark-green and so on.
Flowers of herbaceous peony are usually grown alone at the top of the stem or near the leaf axil. Flowers of the original species are white, 8 to 11 cm in diameter, 5 to 13 petals, obovate.

There are 11 species in China, mainly distributed in the southwest and northwest regions, and a few species are also distributed in the northeast, North China and the provinces along the Yangtze River. P. suffruticosa and P. lactiflora are one of the main medicinal materials in China. They are cultivated in many areas of the country, especially in Sichuan, Henan, Shandong, Anhui and Zhejiang.
