CONTINUOUS BLOOM IN AMERICA 



the cold-frame, or wherever they are to winter. In 

 April they may be moved to the garden. If Dian- 

 thus and Snapdragon and Forget-me-not are moved in 

 early April, it is well to supply them for a while with 

 a light protection of leaves or hay in case of a severe 

 spring frost. Dianthus is the hardiest of this class, 

 and will sometimes survive winter in the open, if not 

 moved too late in the fall. 



Campanula medium, when large enough, should be 

 transplanted in the open nursery 6 inches apart, and 

 again transplanted to the cold-frame in September, 

 set 8 or 9 inches apart. By April 15 it can be safely 

 moved to the garden. 



Third Class 



Spring-Planted Only. — The third class of hardy an- 

 nuals, those sown only in spring. Zinnia, etc., although 

 classed as hardy, if started early under glass, are on 

 this account more tender than when sown in the open. 

 They should, therefore, not be set out before May 20, 

 when severe frost no longer threatens. If they have 

 been sown in the open, they can be transplanted when- 

 ever convenient. 



TENDER ANNUALS 



The tender annuals sown under glass should not 

 be moved to the garden until after all possibility of 

 frost, which is the last of May near New York.
