12 FAMILIAR GARDEN FLOWERS. 
splendid bloom. It is usual to peg them down when in 
beds, but they thrive better and look better when allowed 
to stand up, and therefore petunias are well adapted to 
form low flowery hedges in the flower garden. In Paris 
they are much employed in this way in combination with 
white “ marguerites,” the result being a dense hedge of 
about a foot to a foot and a half in height, composed of 
two close lines of purple and white flowers. When enclosing 
asmall plot of grass this is very effective. 
The named varieties are propagated from cuttings in 
July and August without the aid of artificial heat. The 
best place wherein to winter them is a cold dry pit, for 
damp is death to them; they cannot endure a touch of 
frost, and, generally speaking, the greenhouse is too warm. 
When kept sufticiently cool they are entirely free from 
vermin ; indeed, the amateur gardener may with advantage 
regard as a doctrine that the liability of a plant to the 
attacks of vermin is in direct proportion to mismanage- 
ment in respect of temperature and moisture; generally 
speaking, when a plant becomes covered with “fly” or 
“spider,” it is the consequence of insufficient ventilation.
