x LILY OF THE VALLEY, 
For forcing, and making plantations out of doors. 
The Berlin Forcing Crowns offered below we re- 
commend for general forcing, to come in after Christmas. 
For flowering before and at Christmas the Retarded 
Crowns should be used. For outdoor culture the Planting 
Crowns are recommended. 
DIRECTIONS FOR FORCING. 
Plant 15 to 20 crowns in a 5-inch pot, shaking in a little 
light soil amongst the roots, until they are tightly potted ; 
leave the crowns free above the soil and a little below the 
rim of the pot. Place on bottom heat in a moist atmosphere , 
with a temperature of 80 to 85 degrees (if forced in March 
a temperature of 70 to 75 degrees will be sufficient), and 
cover the crowns with a little cocoa fibre or moss, which 
remove when top growth is showing. Tepid water should 
be frequently given, care being taken that it penetrates to 
the centre of the clump. To encourage simultaneously the 
development of flower and foliage, keep a flower-pot inverted 
over the crowns, until flower and foliage have made some 
progress, when gradually admit light. A dry atmosphere , or 
an insufficient supply of water at the roots , will cause the 
crowns, technically speaking, to go “blind.'’ Where large 
quantities of Lily ot the Valley blooms are required foi 
cutting, the crowns should be planted rather thickly in 
boxes and receive the treatment described above. 
OUTDOOR CULTURE OF LILY OF THE VALLEY. 
Out-of-doors the Lily of the Valley likes a partially shaded and moist situation. The best results are 
obtained on a shady border against a wall, placing the crowns 6 to 9 inches apart and leaving them 
to establish themselves. The soil should be a good loam enriched with manure and a top dressing 
of old manure should be given annually. The plants should not be allowed to remain more thao 
three years in one spot.

RETARDED LILY OF THE VALLEY, 
Suitable to force for Autumn, Winter and Summer flowering. 
The earlier plantings of the Berlin Retarded Crowns will give bloom in about three weeks, 
but the crowns started in November and December require a little more time. It is necessary 
that they be planted as soon as received, and grown on rapidly without any check. In June, July, 
and August all that is needed is to place them in a cold frame, and they come along quickly 
with very little attention. Later on however, when the nights become cool, the temperature must 
be raised to that of the day. Failures sometimes occur with these retarded crowns in October, 
November, and December because they are not given the warmth they require at night. 
The plants should be kept fairly dry overhead, and a warm moist atmosphere should be maintained. 
As the retarded crowns make a vigorous foliage it is advisable to remove one out of three leaves, 
as this will assist the development of the flower spike.
