TEMPERATURE 
The word “Intermediate” following a heading of the plant lists, 
means these plants do best in a house whose minimum temperature is 55° 
to 65° at night. A night heat of 55° as a minimum on extreme cold nights, 
and 60° in moderate weather will be better for the plants than a higher 
temperature, especially if they are in bloom. 60° or 75° by day, or a few 
degrees more with sun-heat and ventilation is good, and in summer, as low 
as outside conditions will permit. “Warm” means a minimum temperature 
of 65° to 75°. “Cool” means a minimum temperature of 45° to 55°. We 
have indicated in each case the type of house each variety prefers, but this 
is not an absolutely hard and fast rule, for we have repeatedly seen 
gardeners successfully growing mixed types in one house by the careful 
utilization of the various parts of the house for individual plants that need 
the cooler end, or the warmer end, conditions that are soon discovered by 
the observant cultivator.
