may be propagated by division of the root, as Arctotis argeiitea, Ancilema nudi- 
Jiora, fyc. Others, such as Anchusa capensis, Hinnea elegans , Cynoglossum 
pictum , Manulea cheiranthus , &c. can only be propagated by seeds, which will, in 
general, ripen pretty freely. 
Stove Biennials. — These require similar treatment to stove annuals (page 20) 
until they arrive at maturity. They may then be mixed among the other stove 
plants, and either be plunged in bark or otherwise, as may be found necessary.

CULTURE OF THE GENUS DIANTHUS. 
Almost all the species of this genus are held in great estimation, some for 
their peculiar beauty, and others for the delightful fragrance they emit. The 
annual species and varieties, as covymbosus , armeria , &c. require only to be sown as 
other annuals in the open border. The perennial herbaceous species differ very little 
as to their mode of treatment. 
The Dianthus Barbatus, or Sweet William, is an old and well-known 
inhabitant of our gardens, and was much esteemed many years ago. The seed 
should be sown in May, with the other biennials. Prepare a bed of light earth, suf- 
ficiently large to hold the number of plants required ; sow the seed, and cover it 
lightly, keeping it clear from weeds during the summer; early in August they 
may be removed, and planted in the places where they are intended to flower, or, if 
it is not convenient to remove them in August, they may remain in the seedling 
bed until the arrangements are made in the spring. 
This treatment will answer for all the species and varieties of similar habits to 
the Sweet William, as aggregatus , latifolius , &c. The dianthus hybridus, or mule 
Pink, so well known and much prized in our gardens, is probably a variety betwixt 
Poiret’s Pink, and the common garden Pink, or betwixt the former and the Carna- 
tion. It requires the same treatment as the common Pink, which will be treated on 
hereafter ; the culture of which, together with the Carnation and the Sweet 
William, may be taken as standards for the whole genus.
