SOWING HAKDY ANNUALS 141 



Tender perennials, such as Begonias, Coleus, etc., 

 must be sown under glass in January. 



SOWING SEEDS IN THE OPEN. 



Seeds of biennials, such as Canterbury Bells, 

 Campanula pyramidalis, and also of Wallflowers, 

 should be sown in May, in pans or boxes, kept in 

 shade under a wall facing north, and, as soon as 

 large enough, pricked out into beds in the open, in 

 half shade ; they can grow there until the autumn, 

 when you may put them into their flowering 

 quarters. 



Seeds of all hardy perennials can be treated in 

 the same way, sowing them as soon as they are 

 ripe. In the case of late seedlings which are still 

 small when the wintry weather begins, you had 

 better leave them in their boxes so that they may 

 be sheltered in frames during very severe frost. 



SOWING HARDY ANNUALS. 



Some hardy annuals are best if sown in August 

 or September, for they make much better plants 

 for flowering the following year ; such are, Love-in- 

 a-Mist, Cornflowers, Silene pendula, which can be 

 transplanted to the place in which you want them
