Robert Fortune, the great explorer of the Royal Horticultural Society, made four trips to China and introduced many fine plants to England. In 1846, he brought twenty-five of the finest tree peonies ever to come out of China. Among these were 'Atrosanguinea,' 'Berenice,' 'Bijou de Chusan,' 'Dr. Bowring,' 'Globosa,' 'Glory of Shanghai,' 'Lord Macartney,' 'Pride of Hongkong,' 'Robert Fortune,' 'Samarang,' and 'Zenobia.' These were enthusiastically received and quickly propagated, so that both British and continental nurseries cataloged them in some quantity in the 1860's.

After forcing, tree peonies require two or three years for recuperation. Because the blooms of double-flowered varieties last longer upon the plant, those varieties are best for forcing. Reine Elizabeth, Lactea, Jules Pirlot and Lord Macartnay are excellent for this purpose.

The Tree Pæony. 
...For the last twenty years or longer we have had to look to our French neighbours for new sorts of Tree Pæony, for since they have taken the work of hybridising and raising seedlings in hand they have supplied us with all the finest sorts.  Until now the list is long- too long, in fact, for names are given where very shadowy differences exist.

Chinese Tree Pæonies. — Pæonia Moutan.
These are the most splendid and showy of all flowering shrubs, and among the most rare.
The flowers are mostly fragrant, and all are double, unless denoted otherwise.  They are perfectly hardy, and will withstand the winters of our most northern States and the Canadas.  They bloom in May, ten to fifteen days before the Chinese Herbaceous varieties.
The following are distinct new Chinese Varieties obtained by Robert Fortune; and, as they are the most rare and valuable varieties, the prices will be regulated according to their size.

MOUTAN PAEONIES INTRODUCED FROM CHINA.
BY MESSRS. STANDISH AND NOBLE, BAGSHOT NUBSEBY.
Of the many remarkable plants imported by us from China, these, if judged by the size and beauty of their flowers, are among the most attractive. In the magnitude of their individual blossoms, in the diversity and richness of their colours, as well as in the profusion in which they are produced, nothing remains to be desired. The following sketch will afford an idea of their general characters. First, of colour: of white there are examples unsurpassed in intensity and clearness by any other flower, not excepting even the old double white Camellia. Of rose colours there are many shades, as well as of purples, and one rivalling the richness of the Tuscan rose. Then there is a pale blush, light red, deep red, salmon colour, primrose, peach colour, and crimson; with various other tints and combinations of these already mentioned. Some of the light-coloured ones have the bases of their petals deeply stained with red or purple; others are delicately shaded. Most of the flowers are very double; some are, however, only semi-double, the latter generally have the petals stained as described. In shape many are finely cupped; more resemble the finest rose, and others have anemone flowers. Of the last named, a white and a deep red are fine examples. In size, too, they are remarkable; some of the flowers produced last season, and from small plants, measured eight, ten, and twelve inches across.....
