loo PLANT CULTURE 



bears large flowers. The plants may be grown with Cattleyas. 

 If kept in a healthy condition at the roots this is a very free bloomer. 

 The potting material should be examined after the flowers are gone, 

 and if decayed replace with fresh material. In large specimens this 

 is a tedious operation. As the plants are evergreen, they should 

 never become very dry. A good size for flowering may go into 

 lo-inch pans. By the beginning of June we place our plants under 

 the shade of trees for four months, where they develop splendid 

 growth. Their flowering season is during February and March, and 

 immediately after, the shoots being to push out. 



Propagation. The plants of this species are easily divided. 

 New growths sometimes push out not only from the base of 

 last year's pseudo-bulb, but also from those of the two previous 

 seasons. 



COCOS. C. Weddelliana in a young state is exceedingly 

 •ornamental, the leaf divisions being narrow and close together. 

 It wiU stand a lower temperature than is generally given. Small 

 plants are admirably adapted for the dwelling house. C. nucifera, 

 the Cocoanut, is also cultivated in greenhouses. C. plumosa is 

 a prominent street tree in California and Florida. (See also 

 Palms.) 



CODIi€;UM (Croton. Variegated Laurel). The Codia;um, 

 or Croton, as it is commonly called, is a genus of plants containing 

 almost endless varieties through crossing and selection. It is a 

 foliage plant and is noted for its varied and brilliant markings on 

 the leaves. They are tropical plants and therefore grown only in 

 greenhouses in the North. In the warmer parts of the country it 

 has forged its way to the front as a choice bedding plant and very 

 deservedly so. (See page 283). It is seldom seen as a house plant, 

 one reason being the dry air of houses. Some of the many varieties 

 noted are: Baroness James de Rothschild, Rex, Robert Craig, 

 Maculatum, Queen Victoria, Norwood Beauty, Punctatum. 



Culture. They require a night temperature of from 70 to 75 

 degrees and the air must be kept moist by frequent syringing. The 

 color of the leaves will be enhanced by an increase in the sunlight. 

 They are subject to mealy bugs and red spider and should be 

 sprayed two or three times a week with tobacco water. 



Propagation. They may be increased by cuttings of half- 

 ripened wood taken at any time from October until June. A bot- 

 tom heat of 80 degrees is required.
