Peony. The peony or paeony is a flowering plant in the genus Paeonia, the only genus in the family Paeoniaceae.
   They 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 is 33 known species.
   The relationships between the species need to be further clarified. Most are herbaceous perennial plants 0.25-1 metre tall, but some are woody shrubs 0.25-3.5 metres 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 only 7-10 days.
   Peonies are among the most popular garden plants in temperate regions. Herbaceous peonies are also sold as cut flowers on a large scale, although generally only available in late spring and early summer. An emerging source of peonies in mid to late summer is the Alaskan market. Unique growing conditions due to long hours of sunlight create availability from Alaska when other sources have completed harvest. All Paeoniaceae are deciduous perennial herbs or shrubs, with thick storage roots and thin roots for gathering water and minerals. Some species are caespitose, because the crown produces adventitious buds, while others have stolons. They have rather large compound leaves
