HOUSE PLANTS lib 



HOUSE LEEK. Sempervinim tectorum. 



HOUSE PLANTS (Figs. 1102-1104) are those plants 

 which can be grown in the ordinary rooms of dwelling 

 houses. They may be hardy or tender; but only such as 

 are suitable for this purpose will be considered here. 



In the living rooms of the modern well-built house, 

 plants must contend against difficulties which did not 

 exist in the less carefully equipped dwellings of fifty 

 years ago or earlier. The present methods of heating 

 and lighting, by gas or kerosene lamps, not electricity, 

 produce a dry atmosphere which is inimical to vegetable 

 growth. In houses lighted by electricity, and heated by 

 any system which introduces fresh air in abundance, 

 this matter is not so troublesome. Too much heat and 

 dry air are harder for plants to endure than insufficient 

 light, but it is also lack of light which makes it so 

 diflicult to grow flowering plants in houses. Dust 

 and insects do harm, but these difficulties can be 

 overcome. 



For the above reasons it is important to select 

 House Plants which are adapted to resist a dry at- 

 mosphere, a high temperature and inadequate light. 

 Such examples can be found among certain tropical 

 plants with coriaceous leaves and small stomata, 

 what the florists call foliage plants, e. g., rubber 

 trees, palms, etc. These make the best foundation 

 upon which any successful system of growing plants 

 in houses can be built. Fluvrniii.' pliiTits .-an also be

 or in bloom, and not fousid. nd a part of tin- perma- 

 nent arrangement. After flowering they should be re- 

 moved: their function is not unlike the use of cut- 

 flowers, but they last longer and are not much more ex- 

 pensive, while they largely increase the attraction of 

 the window-garden. 



The best rooms for plants are those which get the 

 most sun, and the best positions are those nearest the 

 windows, where there is not only more light but more 

 fresh air. A large palm, fern or rubber will grow in an 

 entry or poorly lighted corner, but the best pi ice is that 

 which IS best lighted Plants do well m i kitthen the
