| "Peony or paeony is a name for plants in the genus Paeonia, the only genus in the flowering plant family Paeoniaceae.
They are native to Asia, southern Europe and western North America. Boundaries between species are not clear and estimates of the number of species range from 25  to 40.
Most are herbaceous perennial plants 1.5 - 5 feet (0.5 - 1.5 metres) tall, but some resemble trees up to 5 - 10 feet (1.5 – 3 metres) tall.
They have compound, deeply lobed leaves, and large, often fragrant flowers, ranging from red to white or yellow, in late spring and early summer.
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" - Wikipedia
