over them. These will never flower, however, so early or so elegantly as when 
they have had a good winter protection. 
The C. Youngii may be grown to the height of three feet or more, having from 
150 to 200 flowers in perfection at one time, and in this state it is a most enchant- 
ing object. 
All the annual species and varieties as C. pinnata , &c., should be sown on a 
hot-bed at the same time and in the same manner as other tender annuals (p. 21) 
and when they have grown a sufficient size, transplant them into single pots, and 
place them amongst the other green-house annuals, or place them in warm situations 
out of doors, where if the weather be fine they will flower very well. 
The biennial species and varieties as C. jloribunda , &c., should be sown in 
September, and be treated like other green-house biennials (see p. 66), and they will 
flower the following summer. 
The perennial herbaceous species as C. Yomigii } Gellaniana, &c., are easily 
propagated by division of the roots, and in many cases by cuttings and seeds. 
The shrubby species as C. Morrisoni, angustiflorci, &c., are raised by cuttings 
of half ripened wood, and by seeds. 
Plant the cuttings in light sandy soil ; either in pots which may be plunged 
in a little heat, or in a little bed under a hand-glass, and they will root without 
difficulty. 
If the seeds of either the biennial, herbaceous or shrubby kinds be sown as soon 
as gathered, they produce plants which flower the following summer. But they 
are not so strong as those raised in the spring, which are not allowed to flower till 
the year following. 
When they are of a sufficient size, transplant them singly into small pots, keep- 
ing them in the green-house. Repot when necessary, so that by the end of the year, 
the plants will be very fine, fit for blooming strong the following year, and standing 
in 48 sized pots. 
As soon as the roots push through the holes at the bottoms of the pots, place 
them in pots a size larger, being careful not to disturb the roots more than can be 
avoided. In a month, the roots will again make their appearance, repot them again 
as before. 
About the beginning of March, the roots will again have progressed, the plants 
may then be placed in large pots, the size called half-gallons or twelves. 
Particular attention should now be paid to air and water ; always keeping the 
soil just moist, but never allowing it to be saturated, which must be considered a 
rule at all times. 
At the end of April or beginning of May, remove the plants from the green-
