Heliotropes, 



Mahernias, 



Pelargoniums, 



Roses Tea, Bourbon, and Bengal, 



Solanums, 



Stevias, 



Camellias, Azaleas, etc., etc. 



All of these will flower and grow freely in a green- 

 house temperature, or at an average of not more than 

 fifty degrees at night, with fifteen or twenty degrees 

 higher during the day. 



We add another limited list of plants requiring a high- 

 er temperature, some of them being in other respects 

 more difficult of culture, besides being more expensive : 

 Allamandas, Begonias, 



Bouvardias of all sorts, Euphorbias, 

 Coleus of all sorts, Poinsettias, 



Stephanotis, Ruellia formosa, 



Salvias, etc., etc. 



All of the above will luxuriate best in a humid atmos- 

 phere, at an average of not less than sixty degrees at 

 night, with fifteen or twenty degrees higher during the 

 day. The best aspect for growing plants from October 

 to April is due south. For the intermediate season east 

 is preferable. Watering is a very important operation, 

 but a little experience with plants, and ordinary care in 

 observing will soon show when this is required. A good 

 deal depends upon the condition of the plant ; if in 

 vigorous growth there is but little danger of giving it too 

 much. On the other hand, if the plant lias been cut 

 back or lost its leaves, water should be given sparingly. 

 For example, you may take a vigorous growing apple or 

 pear tree, and saw off its limbs to the trunk in mid- 

 summer ; if its roots are kept saturated with moisture it 

 will die, but if kept dry it will shortly again develop 

 branches and leaves. This example teaches us a lesson
