LIGHT, HEAT AND VENTILATION 



such forms as are suitable for the particular ex- 

 posure. Often sun-loving and shade-loving 

 plants may be arranged in the same w^indow, 

 by placing those requiring sunshine in the center 

 and the others at the side. (Fig. 17.) 



Where the window is a south or west one, with 

 full exposure to the sun, blooming plants, as a 

 rule, will do well. On the other hand, if the 

 window is a north or east one, the best results 

 are secured with foliage plants. This, however, 

 does not exclude flowering plants from the east, 

 or foliage plants from the south and west win- 

 dows. 



TEMPERATURE 



Although most plants suitable for house cul- 

 ture may be grown in a temperature of from 

 60 to 70 degrees F., yet every plant has a definite 

 range of temperature in which it makes its best 

 growth. This range of temperature, however, 

 is not limited by the maximum and minimum at 

 which the plant will grow. When the tempera- 

 ture is above this optimum range the plant of- 

 ten becomes drawn, due to the forced growth; 

 when below it, it becomes stunted.
