Paeonia
Also called Paeony, Peonies
Peonies are a genus of flowering herbaceous perennials and woody shrubs with large, often fragrant blooms in spring and early summer. Most grow in cool temperate climates and need a cold winter period to flower well.
The peony or paeony () is any flowering plant in the genus Paeonia, the only genus in the family Paeoniaceae. Peonies are native to Asia, Europe, and Western North America. Scientists differ on the number of species that can be distinguished, ranging from 25 to 40, although the current consensus describes 33 known species. The relationships between the species need to be further clarified.
Most are herbaceous perennial plants 0.25–1 metre (1–3 ft) tall, but some are woody shrubs 0.25–3.5 metres (1–11 ft) tall. They have compound, deeply lobed leaves and large, often fragrant flowers, in colors ranging from purple and pink to red, white or yellow, in late spring and early summer. The flowers have a short blooming season, usually lasting for only 7–10 days.
Ancient Chinese texts mention the peony was used for flavoring food. Peonies have been used and cultivated in China since early history. Ornamental cultivars were created from plants cultivated for medicine in China as of the sixth and seventh century. Peonies became particularly popular during the Tang dynasty, when they were grown in the imperial gardens. In the tenth century the cultivation of peonies spread through China, and the seat of the Song dynasty, Luoyang, was the centre for its cultivation, a position it still holds today.
A second centre for peony cultivation developed during the Qing dynasty in Cáozhōu, now known as He Ze. Both cities still host annual peony exhibitions and state-funded peony research facilities. Before the tenth century, P. lactiflora was introduced in Japan, and over time many varieties were developed both by self fertilisation and crossbreeding, particularly during the eighteenth to twentieth centuries (middle Edo to early Shōwa periods).
The genus Paeonia naturally occurs in the temperate and cold areas of the Northern Hemisphere. The section Moutan, which includes all woody species, is restricted in the wild to Central and Southern China, including Tibet. The section Onaepia consist of two herbaceous species and is present in the West of North-America, P. brownii between southern British Columbia and the Sierra Nevada in California and eastward to Wyoming and Utah, while P. californica is limited to the coastal mountains of Southern and Central California.
The herb known as Paeonia, in particular the root of P. lactiflora (Bai Shao, Radix Paeoniae Lactiflorae), has been used frequently in traditional medicines of Korea, China and Japan. In Japan, Paeonia lactiflora used to be called ebisugusuri ("foreign medicine"). Pronunciation of 牡丹 (peony) in Japan is botan. In kampo, the Japanese adaptation of Chinese medicine, its root was used as a treatment for convulsions. It is also cultivated as a garden plant. In Japan, Paeonia suffruticosa is called the "King of Flowers" and Paeonia lactiflora is called the "Prime Minister of Flowers".
