Answer:

Many Japanese tree peonies are Chinese tree peonies with Japanese names. The garden tree peony was brought to Japan from China at the beginning of the 17th century. The Japanese, in an aesthetic decision, chose to grow plants that have single or semi-double flowers, grow 4 to 6 ft. high, and (with some notable exceptions), have little or no fragrance. Chinese tree peonies range in form from single to complex double shapes, and many cultivars are fragrant.

 Answer:

The Chinese tree peony is the "National Flower of China". This accolade comes from a recognition of the plant's numerous flowers, and that the color of the flowers defy representation even in photos or watercolors. In bloom they have a luminous quality as well as subtle shades and tone that gives them the appearance of being made of silk. The envelope of fragrance from older plants is an experience that stays with a garden visitor long after they have left the garden. They are also extremely long lived plants, with reports from China of plants living for more that two centuries.

 Answer:

Tree peonies are very long lived woody shrubs that grow to about 4 ft. tall and wide. They prefer a part sun location. They have long fibrous roots and woody stems.The woody branches are not cut down in fall, because they have buds formed for spring blooms. Flowers are very large and usually require no staking.They are known as Paeonia suffruticosa, though this botanical name is under question. Tree peony varieties are almost all hybrids of several species tree peonies found in China.Tree peonies do not require a freeze to bloom, but do need a winter dormancy.

Herbaceous peonies are more familiar to gardeners. They are perennial plants that grow from a bulbous, fleshy root. The green stems produce long stemmed flowers which require support. In the fall, when the weather freezes, the plant dies back to the ground, but comes back faithfully every year.Herbaceous peonies need full sun, and must have a definite freezing period in winter to bloom.
