CONTINUOUS BLOOM IN AMERICA 



for a little over eight weeks. But, as most of the 

 perennials take up much room and bloom but a few 

 weeks, it would require more than the space of an 

 ordinary garden-bed to have a long and continuous 

 "all-over" bloom with nothing but perennials.* 

 Another objection to depending altogether on peren- 

 nials is that the hardiness of some of them is not 

 always to be relied upon. Disease may take them, 

 or if, in an unusually severe winter a quantity are 

 killed, it may be impossible the following spring to 

 replace them satisfactorily. Large grown perennials 

 are diflScult to obtain from the nurseryman, and some 

 varieties take three years to develop a strong bloom. 

 Annuals from good seeds never fail to develop quickly; 

 therefore, the perennial bed should be more or less 

 dependent upon a certain number and variety of 

 annuals. 



* In Chart No. XI, at the end of the book, there is given a suggestion 

 for a bed of perenniab, but it is not as satisfactory as where annuals are 

 included, at least when the flowering season is prolonged.
