they are treated like seedlings." (3) By seeds, started 

 in the greenhouse or hotbed in March or even earlier. 

 The young seedlings should be given plenty of room by 

 transplanting as they grow, and may be set in the open 

 garden by June. If started thus early they flower the 

 first autumn, but the seed may be planted in late spring 

 or summer, care being taken to wal. r will cluiin^' iliv

 be secured in one season by cutting away Ihc lluwcr-

 The Delphiniums are much grown in the open garden 

 and border, and are of great value for cut flower pur
