PAPHIOPEDILUM 



PAPHIOPEDILUM 



2463 



The deciduous tropical species require similar treat- 

 ment to the evergreen kinds. They have a long dormant 

 period during which they should be rested in a tempera- 

 ture of 50 F., with sufficient water to keep the com- 

 post moist until growth starts, when they must be 

 returned to their proper department and enjoy a liberal 

 supply of water until after the flowering season, when 

 they must be ripened off and the water supply gradually 

 withheld. 



The hardy species (true cypripediums) do better 

 planted out in the open ground or in rockeries, where 

 they should be so situated as to have good drainage 

 and shade. The soil must be free and porous and con- 

 sist of three parts chopped turf and equal parts of peat 

 and sphagnum. They require a liberal supply of water 

 and frequent syringing over the foliage while growing, 

 but the supply should be gradually reduced after the 

 flowering period until only enough water is given to 

 keep the soil moist. During the winter the plants should 

 be protected with leaves or pine boughs. Cypripe- 

 dium rcginx and C. pubescens grow well under pot cul- 

 ture. A 7- to 10-inch pot will hold eight or a dozen 

 crowns, which should be planted 2 inches below the 

 surface. Two inches of drainage are sufficient. The 

 pots should be filled with soil (firmly pressed in) to 

 } 2 inch below the rim. After a thorough watering they 

 should be stored in a coldframe and protected with 

 leaves and boughs. About the middle of February they 

 may be removed to a coolhouse, where they should 

 remain for a week, and then be placed in the cool end of 

 the cypripedium house, where they should be watered 

 sparingly until growth-action starts. These plants 

 make strong growths under this treatment, and the 

 flowers are a decided improvement over those produced 

 outside. See Cypripedium and Phragmopedilum. 



All paphiqpedilums are propagated by division, but 

 many beautiful hybrids have been add'ed to the list, 

 since the raising from seed has been better understood.
