IRIS BORDER GARDENS 195 



These iris plants are not expensive. One should be able 

 to buy good clumps for setting out at from fifteen to twenty- 

 five cents each. The German and Siberian Irises increase 

 so rapidly that they 

 should be divided and 

 replanted every third 

 or fourth year. It is 

 therefore easy for a 

 school to obtain a good 

 variety of colors of Ger- 

 man Iris by means of 

 clumps and divisions 

 received as gifts from 

 home gardens. If 

 neighbors possess o r 

 purchase different vari- 

 eties, they can secure 

 good collections in 

 every home yard by 

 means of exchanges. 

 The plants should be 

 divided in August or 

 September: the blos- 

 soming period is then 

 over, the roots are well 

 developed, and time re- 

 mains for the divisions 



to become established before winter. The iris may be trans- 

 planted, or even divided, in early spring, however. 



The beauty of the German Iris is particularly satisfying. 

 While the structure of the flower is similar to that of the other 



German Iris.
