350 FRITZ BAHR'S COMMERCIAL FLORICULTURE 



Of course you can sow Delphiniums out in the open during 

 Summer without a greenhouse, but you can obtain quicker results 

 by starting them under glass as stated above. 



DEUTZIA 



Of most value to the florist among the fine flowering shrubs 

 is Deutzia gracilis, for as a pot plant in bloom it is most desirable 

 for Easter or early Spring flowering when its branches are loaded 

 down with the small, white, bell-shaped flowers. 



For best results let your nurseryman supply you in Spring with 

 small, field-grown stock which should be potted up into 5s or 6s and 



Fig. 146. — ^Deutzia gracilis. Deutzias grown on in pots during Summer force 



easily for Easter and when loaded with flowers and good foliage are most desirable. 



Failure is often the result of too severe forcing or of making use of field-grown 



stock potted up during Winter — which is useful only for May flowering
