CONTINUOUS BLOOM IN AMERICA 



Plate VI.) When such perennials as Armeria, Achil- 

 lea tomentosa or Clove Pinks are grown in the front 

 line, there is nothing left by mid-June but their ever- 

 green foliage. If these plants should be alternated 

 with strong, long-blooming annuals, such as Ageratum 

 and Verbena, the latter would soon creep over their 

 perennial friends, which, for lack of light and air, 

 must turn sickly and will probably die. In a bed 

 for continuous bloom, it is impossible to plant in 

 effective alternation along the whole length of the 

 edge all the perennials that would be required to rep- 

 resent the various periods until frost. 



If, however, it is desired to diminish the quantity 

 of annuals required for an edging, the following combi- 

 nation with perennials is suggested for one bed at least. 



Plant the hardy, silvery, bushy Santohna incana 

 every 24 inches, and between plant groups of Cottage 

 TuUps. 



Then plant in May, around the Tulips, a few Agera- 

 tiun, white in some spaces, blue in others; or add to 

 some of these spaces other all-summer blooming an- 

 nuals, not much taller than the Ageratum. 



Of the low growing perennials for an edging. For- 

 get-me-nots, Viola comuta. Campanula Carpatica, and 

 blue Plumbago bloom the longest. Plumbago, with 

 one or two of the others named, could be satisfactorily 

 used without annuals when the garden is to bloom only 

 in May, June, and September.
