CHAPTER XVIII 

 AN IRIS CALENDAR 



THE following list is not intended to be absolutely ex- 

 haustive, and only includes those species that are easily 

 obtainable. The few exceptions, e.g. dichotoma and 

 chamceiris X trojana, are included in order to show that 

 some Irises may be had in flower even in August and 

 September, though neither of these plants is commonly 

 to be found in catalogues. 



The dates for planting and transplantation are not the 

 only possible times, but the best times the times, that is, 

 at which the plants, given ordinary conditions, most quickly 

 become established in the ground. In most cases Irises 

 may be planted at considerably later dates than those 

 mentioned, but there is then always the risk that an excep- 

 tionally hard winter will either cripple the plants or kiH 

 them outright, or at least prevent any display of flowers in 

 the following season.
