Tree Pæonies.  Pæonia Arborea.
This beautiful group of shrubs is among the oldest of introductions from Japan, but magnificent new varieties have been added from year to year until we have a long list of wonderful forms.  They are quite distinct from the herbaceous section, and have shades of color not found in the latter; and when once established form compact bushes, which in spring are covered with the gigantic blooms.  These pæonies are a little tender in exposed situations north of Boston; but if planted in a sheltered, warm location, and protected during the first two winters by a covering of pine boughs, or other loose material, will eventually establish themselves, and form one of the most decorative features of the garden.  Like the herbaceous kinds, they enjoy rich soil, and the blooms last longer and come finer when partially sheltered from the hot sun.  They are well worth the little trouble entailed in their cultivation.  We can offer strong plants of the leading and most hardy kinds; but as they are slow and difficult of propagation, this fact will account for their relatively higher cost over the herbaceous kinds.  Having secured a large stock of these beautiful plants, we are enabled to offer them at lower prices than ever before.  2 year plants, 75 cents each; 3 year plants, $1.00 each.

Moutan Paeonies in pots.—Although it is a century since the Moutan or Tree Pæony was introduced into this country, it is by no means a common plant, and is not grown nearly as much as its merits deserve.  Many of the new varieties far excel the typical form both in size and colour of the flowers.  Pæonies will not force early, but grown as pot plants and kept in a cold frame, they produce a grand display of bloom at this time of year.  Being gross feeders they require liberal treatment, and should never be allowed to get dry.  Amongst the best varieties are Reine Elizabeth, Comte de Flandres, Caroline, Impératrice Josephine, and Salmonea.  A fine group of these is a great attraction in the greenhouse at Kew. — F. G.

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.

The Best Tree Peonies.
The following list contains some of the very best varieties of tree Peonies or Moutans at present in cultivation; I obtained it from my friend M. Charles Verdier, of Paris, who makes Peonies his special study; among them, as will be seen, are few novelties, but M. Verdier states that the newer varieties are generally inferior to the older kinds:
Comte de Flandres, very large, rose...
