PLANTS FOR WINDOW GARDENING. 57 



plant bears the knife well, and breaks freely, so it can be 

 trained into any shape. 



The common variety is H. corymbosum, then the oldest, 

 H. Peruvianum ; H. Volterianum is a fine dark variety, 

 but not so strong growing. 



Florists' catalogues contain many varieties, but the above 

 are the best for general culture. 



THE SALVIA. 



This plant is only valuable as a window plant in summer 

 and early autumn. The chief variety cultivated is the Scarlet 

 Mexican Sage (S. splendens), introduced from Mexico about 

 forty years ago. It is a rank growing shrub, with long, 

 jointed stalks, crowned with rich, scarlet flowers. The best 

 way to grow it is to set the plant in rich soil in the garden 

 in spring. It will grow vigorously. About the last of 

 September pot it (it transplants easily), shade it for a few 

 days, then remove it to a sunny window, where it will 

 delight you with its brilliant blossoms for two months. 

 Then keep it cool until spring, and repeat the operation 

 until the plant becomes so large as to be unmanageable ; 

 then spring cuttings must be taken off and rooted.
