IRIS 



THE BULB BOOK 



IRIS 



ticular species or variety is limited, it 

 is better to grow the plants in pots or 

 pans. In this way they can be looked 

 after more easily, but must be properly 

 supplied with moisture during the 

 growing period. 



When seeds are ripened, they should 

 be sown in rich gritty soil in well- 

 drained pots or pans, and kept in cold 

 frames. For two or three seasons the 

 young plants should be grown singly 

 in small pots, or several in a large one, 

 until sturdy enough for the flower- 

 border. 



ALPHABETICAL LIST OF SPECIES. 



The following is a short descriptive 

 list of the best Irises met with in 

 gardens, and arranged in alphabetical 

 order. The word "fall" means the 

 three outer segments, and the word 

 " standard " means the three inner

 petal-like stigmas, each one usually 

 sheltering a single stamen in the 

 centre, must not be confused with the 

 falls and standards.
