GREENHOUSE AND CONSERVATORY PLANTS 91 



with bottom heat. The young plants will thrive in heat and mois- 

 ture during the first two or three months; they may afterward be 

 grown in a frame. 



CESTRUM. Some of the species, especially C. corymbosum 

 and C. Newelli, may be used for flowering about Christmas. 



Culture. Keep in a sunny house, or the plants are apt to 

 make too much fohage. 



Propagation. Young plants are started about the end of 

 August, the wood to be taken from old specimens planted out. As 

 soon as rooted put in 3-inch pots, afterward placing three together 

 in a 6-inch pot to bloom. 



CHAM/EROPS. Resembling the Latanias, C humilis, is one 

 of the commonest and most widely cultivated Palms. Being one of 

 the hardiest of all Palms, it is well suited to a house with a varying 

 temperature. (See also Palms.) 



CHORIZEMA (Tango Plant). For several years an old con- 

 servatory plant has been in commercial prominence. It is Chorizema 

 cordatum var. splcndens. The graceful plants with Holly-like leaves 

 and orange and red Pea-like flowers are most attractive. Other sorts 

 are also found, namely, C. Uicifolium and C. varium. 



Culture. The plants should be shifted gradually to 5- or 6-inch 

 pots, using plenty of peat. They may be placed in frames when 

 the weather permits and given a little shade. Pinched frequently, 

 the stock becomes branchy. Syringe often. In order to avoid 

 overwatering, the pots should be filled high with soil; this will neces- 

 sitate watering oftener, but it seems safer. During August or Sep- 

 tember the plants will be covered with long branches and then they 

 should be tied into their flowering shape. Use wires bent to a 

 slightly gobular form and place in the pots. Tie the branches on 

 the wire, spacing them nicely. In a- short time buds will spring 

 from the axils of the leaves. Staked plants are more sightly and 

 take less bench room. During Autumn and early Winter the plants 

 should be kept cool, 40 to 45 degrees at night. If they are a trifle 

 slow they may be moved to a warmer house, but by keeping cool 

 some may be so retarded that they will bloom until April. In order 

 to give the plants air and space they maybe set upon inverted pots 

 in the bench. The plants are best kept from year to year by plung- 

 ing in a bed of ashes during the Summer. 



Propagation. Chorizema ma}^ be propagated by seed or cut- 

 tings. The cuttings root easily in the cutting bench with a tem-
