The Cultivation of Flowers

BIENNIALS 
Biennials are those plants which are sown one year and 
make a considerable part of their growth, but which finish 
their growth the following season, produce their flowers 
and seed, and then die away entirely. 
Wallflower. — The common Wallflowers are examples 
of this class. The seed may be sown on a border from 
March to July, according to the climate and the time that 
it is wanted to flower. It may be sown thinly in drills 
1 in. deep and 1 ft. apart. When the seedlings are about 
2 in. high they should be pricked out into a nice border 
of fairly rich soil, in rows 18 in. apart, and 12 in. between 
the plants in the rows. Dull weather should be selected, 
if possible, for this work, and frequent waterings should 
be given until the plants take to the new soil. The hoe 
should also be kept going to kill the weeds, and let the air 
into the roots of the plants. 
When the summer plants have died they may be cleared 
from the beds or borders, which should then be well dug 
over. If they have been well manured for the summer 
plants no manure will be required, as these plants must not 
grow too rank or soft, or they may be killed by the frost 
during winter. They may be planted in their permanent 
quarters, from 1 2 to 1 5 in. apart each way. 
Myosotis (Forget-me-not). — This is another ex- 
ample of a useful' biennial. The seed may be sown during 
April or May, in drills -f in. deep, and 1 2 in. apart. When 
the seedlings are large enough they should be pricked out 
on to a border, in rows 1 ft. apart and 6 in. between the 
plants.
