CHAPTER XL 



TENDER PERENNIAL PLANTS. 



By the help of artificial heat in green-houses, the list 

 of natural materials for ornamental gardening is much 

 enlarged. We go towards the equator and collect at- 

 tractive species, and by preserving them from the cold 

 in winter, can turn them out in summer, and thus are 

 able to enjoy something of tropical vegetation in the 

 North. Lack of space forbids giving much attention to 

 this subject here, but several lists are introduced, in 

 which are named the leading kinds of plants used for 

 adorning pleasure grounds, and where further informa- 

 tion is wanted, the reader is referred to books on flori- 

 culture, and to the catalogues of florists.
