It is with regret that we thus confine ourselves to a dry list of border 
flowers ; but to classify and characterize them with anything like jus- 
tice would require many pages. Within the last few years great acces- 
sions of desirable plants have been made to our stores. The Lupines and 
Pentstemons from Columbia River, the Verbenas and Calceolarias from 
South America, and the Potentillas and Geraniums from Nepal, have in a 
great measure changed the face of our flower gardens. While our riches 
have multiplied, the difficulty as well as the necessity, of making a selection 
has also increased. 
Most herbaceous perennial plants are propagated by parting the roots, or 
by cuttings ; but some more conveniently by the sowing of seed. 
Biennial Plants.—Plants whose existence is limited to two years, in the 
latter of which they flower and then decay, are called biennials. Many of 
them possess considerable beauty ; and by their easy propagation, and rapid 
growth, they afford aready means of decorating borders. The following 
may be considered most worthy of notice : Agrostemma coronaria; Antir- 
thinum majus; Hedysarum coronarium; Lunaria biennis; Campanula 
media ; (inothera sinuata, biennis ; Verbascum formosum, Althea grandi- 
flora, Scabiosa atro-purpurea, Mathiola simplicicaulis, Digitalis purpurea, 
var. monstrosa or campanulata, Erysimum Perowfskianum. (£nothera 
Drummondii ; Iberis Tenoriana ; Althea grandiflora ; Linaria tristis; Ma- 
thiola incana; Cheiranthus fruiticulosus, with double flowers; Lunaria 
biennis, or moonwort, the large silvery silicles of which are more ornamental 
than its flowers; Frasera carolinensis; Ammobium alatum; Anchusa 
italica; Erytholena conspicua ; French Honeysuckle. When a very de- 
sirable variety of any plant is procured, such as the striped Antirrhinum 
magus, or double varieties of Wall-flower, Sweet William, or Mule Pinks, 
attention should be paid to the striking or cuttings during the summer, as 
the only sure means of continuance. 
Biennials are sown in beds in the end of spring, and are generally trans- 
planted in the course of the autumn into the places where they are intended 
to stand, that they may be confirmed before winter, and shoot up readily 
into flower in the following summer. 
Annual Plants.—Many of the annual species, though of fugitive duration, 
are possessed of much beauty of hue and elegance of form. They are fur-
