Tree peonies or Rock's peonies are deciduous shrub, having spectacular large, often fragrant flowers growing up to 17cm across.
The simple or double petals, surrounding bright yellow stamens come in shades of red, pink, yellow, and white and other striking colors.
Tree peony is long lived and may reach a height and spread of 2-2.5 m (6-8 feet) and often may delight several generations with its beautiful flowers. Some species can live up to 100 years but they don't like to be moved, so choose wisely the place you want to plant them.
Like all peonies, tree peonies need full sun or partial shade and fertile, well drained soil. No special care is needed.
In autumn, tree peonies lose their leaves but the woody stems stay throughout the year.
Fall pruning is not necessary, they don't even like it, though old branches can be cut once in a while to maintain shape and size but not more often than in 3 years.
