Pæonia Arborea (Tree Peonies)
The Tree Peony is really one of the finest plants available for the garden or the conservatory; it is quite hardy and does well under the simplest treatment. The smallest one will flourish in the most astonishing manner, bearing blossoms from 6 to 8 inches across, which will increase every year in beauty and size. In colors, the flowers range in great variety, from a white to a nearly reddish black. [...]

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.

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 imported varieties.  We can supply extra size plants of most of the varieties, at a moderate advance in prices.
