296 FRITZ BAHR'S COMMERCIAL FLORICULTURE 



If you want it for Fall, sow outdoors about the middle of July and 

 it will be in full flower by the end of September, a time when you 

 have use for yellow and brown flowers. It wouldn't pay the retail 

 grower to grow this little plant for flowers for the wholesale market, 

 but he should sow some for his own requirements.

CAMPANULA MEDIUM (CANTERBURY BELLS) 



You can grow and flower Canterbury Bells without a greenhouse, but 

 they can be grown better in one, and made to bring good returns for 



every retail grower. 



Campanulas, whether the 

 single Canterbury Bells or C. 

 medium calycanthema (the 

 Cup-and-Saucer variety) have 

 been favorites for ever so many 

 years. They are among the 

 most showy of biennials for 

 the hardy border during June, 

 and when gently forced under 

 glass make grand pot plants. 

 Or they can be used as cut 

 flowers. They are being grown 

 by quite a few florists, but 

 those who really could make 

 them pay good returns that 

 is, retail growers everywhere 

 pay but little attention 

 to them. 



POT CULTURE FOR EARLY 

 FORCING 



Sow seed about March 

 the greenhouse. Fresh seed 

 will germinate as freely as that 

 of Asters. Transplant the seed- 

 lings into flats and later on pot 

 up into 2s. Keep under glass
