FOLIAGE PLANTS 381 



during the first summer, and should be in six-inch pots by 

 the following September. They lift easily and may be 

 planted out in the garden during the summer. If this is 

 repeated the second year, the growth will be especially 

 strong and vigorous. They are excellent for vases, urns, 

 hanging baskets or window boxes, and large specimens 

 make excellent decorative effects in conservatories. 



Plants in the broad-leaved section like a soil mixture of 

 three parts good turfy loam and one part well-rotted cow 

 manure, with considerable sharp sand worked well into 

 it. They should be given a warm, moist atmosphere and 

 partial shade during the summer, but as fall approaches, 

 they should be gradually accustomed to a drier atmosphere 

 and full sunlight, to develop their colors. These plants 

 are inclined to lose their lower leaves and to become un- 

 sightly.

623. Pandanus, botanical characters. Screw pines are 

 tropical plants often attaining the size of trees. They have 

 many large, aerial roots, and long, sword-like leaves ar- 

 ranged in a perfectly spiral manner like the threads of a 

 screw. The margin of the leaves is sharply serrate, that 

 is, they are saw-teeth. They rarely produce flowers or 

 fruits in cultivation.
