Genome

The basic chromosome number is five. About half of the species of the section ''Paeonia'' however is tetraploid (4n=20), particularly many of those in the Mediterranean region. Both allotetraploids and autotetraploids are known, and some diploid species are also of hybrid origin.

Taxonomy

The family name "Paeoniaceae" was first used by Friedrich K.L. Rudolphi in 1830, following a suggestion by

Friedrich Gottlieb Bartling Friedrich Gottlieb Bartling (December 9, 1798 – November 20, 1875) was a German botanist who was a native of Hanover. He studied natural sciences at the University of Göttingen, and in 1818 took a botanical journey through Hungary and Croatia ...

The composition of the family has varied, but it has always consisted of ''Paeonia'' and one or more genera that are now placed in

. The genus ''Paeonia'' consists of about 35 species, assigned to three sections: ''Moutan'', ''Onaepia'' and ''Paeoniae''. The section ''Onaepia'' only includes ''P. brownii'' and ''P. californicum''. The section ''Moutan'' is divided into ''P. delavayi'' and ''P. ludlowii'', together making up the subsection ''Delavayanae'', and ''P. catayana'', ''P. decomposita'', ''P. jishanensis'', ''P. osti'', ''P. qiui'' and ''P. rockii'' which constitute the subsection ''Vaginatae''. '' P. suffruticosa'' is a cultivated hybrid swarm, not a naturally occurring species. The remainder of the species belongs to the section ''Paeonia'', which is characterised by a complicated

. Known diploid taxa in the ''Paeonia''-section are ''P. anomala'', ''P. lactiflora'', ''P. veitchii'', ''P. tenuifolia'', ''P. emodi'', ''P. broteri'', ''P. cambedessedesii'', ''P. clusii'', ''P. rhodia'', ''P. daurica'' subsps. ''coriifolia'', ''daurica'', ''macrophylla'' and ''mlokosewitschii''. Tetraploid taxa are ''P. arietina'', ''P. officinalis'', ''P. parnassica'', ''P. banatica'', ''P. russi'', ''P. peregrina'', ''P. coriacea'', ''P. mascula'' subsps. ''hellenica'' and ''mascula'', and ''P. daurica'' subsps. ''tomentosa'' and ''wittmanniana''. Species that have both diploid and tetraploid populations include ''P. clusii'', ''P. mairei'' and ''P. obovata''. ''P. anomala'' was proven to be a hybrid of ''P. lactiflora'' and ''P. veitchii'', although being a diploid with 10 chromosomes. ''P. emodi'' and ''P. sterniana'' are diploid hybrids of ''P. lactiflora'' and ''P. veitchii'' too, and radically different in appearance. ''P. russi'' is the tetraploid hybrid of diploid ''P. lactiflora'' and ''P. mairei'', while ''P. cambedessedesii'' is the diploid hybrid of ''P. lactiflora'', likely ''P. mairei'', but possibly also ''P. obovata''. ''P. peregrina'' is the tetraploid hybrid of ''P. anomala'' and either ''P. arietina'', ''P. humilis'', ''P. officinalis'', ''P. parnassica'' or less likely ''P. tenuifolia'', or one of their (now extinct) common ancestors. ''P. banatica'' is the tetraploid hybrid of ''P. mairei'' and one of this same group. ''P. broteri'', ''P. coriacea'', ''P. clusii'', ''P. rhodia'', ''P. daurica'' subsp. ''mlokosewitschi'', ''P. mascula'' subsp. ''hellenica'' and ssp. ''mascula'', and ''P. daurica'' subsp. ''wittmanniana'' are all descendants of hybrids of ''P. lactiflora'' and ''P. obovata''.

. This results in the following relationship tree. One dissertation suggests the section ''Onaepia'' branches off earliest, but a later publication of the same author and others suggests the ''Moutan''-section splits off first. Within that section ''P. ludlowii'' and ''P. delavayi'' are more related to each other than to any other species.

Distribution

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 section ''Paeonia'', which comprises all other herbaceous species, occurs in a band stretching roughly from Morocco and Spain to Japan. One species of the section ''Paeonia'', '' P. anomala'', has by far the largest distribution, which is also north of the distribution of the other species: from the

and François Félix Crousse selected many new varieties, mainly with ''P. lactiflora'', such as "Avant Garde" and "Le Printemps". The Netherlands is the largest peony cut flower producing country with about 50 million stems each year, with "Sarah Bernhardt" dominating the sales with over 20 million stems. 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.

Plant growth habits

Peony species come in two distinct growth habits, while hybrid cultivars in addition may occupy an intermediate habit. * herbaceous: During summer, renewal buds develop on the underground stem (the "crown"), particularly at the foot of the current season's annual shoots. These renewal buds come in various sizes. Large buds will grow into stems the following growing season, but smaller buds remain dormant. The

for the leaves can already be found in June, but the flower only starts differentiating in October, as the annual shoots die down, completing its development in December, when sepals, petals, stamens and pistils are all recognisable. * tree: During the summer, large buds develop at the tip of the annual growth and near its foot. In the autumn, the leaves are shed, and the new stems become woody and are perennial. * Itoh (or "Intersectional"): In 1948 horticulturist Toichi Itoh from Tokyo used pollen from the yellow tree peony "Alice Harding" to fertilize the herbaceous ''P. lactiflora'' "Katoden", which resulted in a new category of peonies, the Itoh or intersectional cultivars. These are herbaceous, have leaves like tree peonies, with many large flowers from late spring to early autumn, and good peony wilt resistance. Some of the early Itoh cultivars are "Yellow Crown", "Yellow Dream", "Yellow Emperor" and "Yellow Heaven".

Flower types

Six types of flower are generally distinguished in cultivars of herbaceous peonies. * single: a single or double row of broad petals encircle fertile stamens, carpels visible. * Japanese: a single or double row of broad petals encircle somewhat broadened

Propagation

Herbaceous and Itoh peonies are propagated by root division, and sometimes by seed. Tree peonies can be propagated by grafting, division, seed, and from cuttings, although root grafting is most common commercially. Herbaceous peonies such as ''Paeonia lactiflora'', will die back to ground level each autumn. Their stems will reappear the following spring. However tree peonies, such as ''Paeonia suffruticosa'', are shrubbier. They produce permanent woody stems that will lose their leaves in winter but the stem itself remains intact above ground level.
