may be sown in spring. When the plants are large enough 
they may be pricked out on a border, in rows 1 ft. apart, 
with 6 in. between the plants, where they may remain 
until the autumn, or even until the following spring, when 
they may be transplanted into their permanent quarters. 
The principal way, however, of propagating herbaceous 
perennials is by division of the rootstock, just before 
growth commences. 
Considerable attention ought to be paid to the arrange- 
ment of the herbaceous borders, the name given to borders 
on which hardy perennials are grown. The varying heights 
must be taken into account. These range from 6 in., in the 
case of the Auricula, &c., through various heights up to 6 
or 7 ft., in the case of healthy Delphiniums. 
Again, artistic taste must be brought into full play in 
the arrangement of the colours. This will apply only to 
plants that are in flower at the same time. No one would 
think of putting a clump of very pale blue Delphiniums in 
close proximity to a clump of deep-blue Campanulas. 
On some soils certain plants will grow higher than one 
expects, and the colours or time of flowering may be mis- 
judged. All these details should be noted during the 
summer, or flowering season, and as far as possible recti- 
fied during the following spring, until the border is quite 
right. 
Another great aim should be to have a good succession 
of bloom for as long a period as possible, from the Christ- 
mas Rose, which pushes its head through the snow, to the 
Anemone japonica , which will flower until the frost cuts it 
down in the autumn. As the plants are of varying heights, 
some will require to be staked. This should be done as
