WHEN TO SOW 



HARDY ANNUALS AND BIENNIALS 



Hardy annuals may be divided into three classes 

 or degrees of hardiness. 



The First Class 



The hardiest of the best hardy annuals are Bluets* 

 (Corn-flower), Silene armeria, Shirley Poppies and Lark- 

 spur,* with the perennial Forget-me-not, var. palustris 

 semperflorens, Anthemis, and Feverfew, treated as 

 hardy annuals. 



Fall-Sown. When sown the previous year in August, 

 these plants, blooming the following May, June, and 

 July, greatly assist in the scheme of continuous bloom. 

 In most climates they survive the winter well in the 

 open ground, needing only a sprinkling of leaves or 

 salt-hay to keep them warm. 



Self-sown in summer and usually germinating in 

 August, they are by nature May and June bloomers, 

 which, with Campanula medium (biennial Canterbury 

 Bell), are quite indispensable to this period the Lark- 

 spurs lasting through July, or later. 



Feverfew and Forget-me-not palustris flower all sum- 

 mer, but, like Viola cornuta, bloom so weakly in the 

 latter half of the summer that for this period at least 

 some gardeners prefer not to depend on them alone. 



* In a warm climate it is better to sow Bluets and Larkspurs not earlier 

 than September 1 to 12 to prevent their growing too tall before winter; 

 they are thus less likely to be broken by snow and ice and more easily 

 transplanted in spring.
