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.
Triomphe de Milan.  Very large, double deep amaranth rose.  Extra.

New Tree Pæonies.
Mrs. Stuart Low.—The flowers of this variety are of great size, with the petals large and not crowded. The outer ones are white, the others of a soft blush-pink hue, except the tips which are white, and the two hues exhibit a delicate blending.
Triomphe de Milan.—The whole of the petals are of a soft rose hue; the inner ones are much narrower, and much cut up into deep segments. The flowers are somewhat different in character from those of the above variety. Both had been grown in pots, and slightly forced. They were exhibited by Messrs. J. Laing & Sons, Forest Hill, at the Royal Botanic Society's spring show on the 23rd of April, who received Floricultural Certificates for them.
