FLOWERING PLANTS 63 
as they are fairly sure to give some of the best flow- 
ers, the worthless singles growing strong and rank 
from the start. Plants growing outdoors during the 
summer may be cut back, potted up and started into 
new growth. The singles bloom more freely than 
the doubles, especially indoors. After blooming, 
cut the plants back to within a few inches of the 
root, repot or give liquid manure and a new growth 
will be sent up, and soon be in blossom again. 
Primroses 
Of the deservedly popular primrose there 
are two types, the Chinese primrose (Pri- 
mula Sinensis) and Primula obconica. Both 
are favorites, because of their simple beauty and 
the remarkable freedom and constancy with which 
they bloom. Another advantage is that they do 
not require direct sunlight. Primroses need no 
particular care. The soil may have a little extra 
leaf-mould and should slope toward the edges of 
the pot, to prevent the possibility of any water 
collecting at the crown of the plant, which must be 
left well above the soil when potting. 
The easiest way to get plants is to buy small 
ones from the florist every spring. They may be 
raised from seed successfully, however, if one will 
take care to give them a shaded, cool location during 
the hot summer months, such as a coldframe cov- 
ered with protecting cloth, or any light material
