HEMEROCALLIS, L. DAY LILY. 

 (Liliacece.) 



This old and popular garden flower is of the easiest culture, which probably 

 accounts for its being found in many gardens. Little need be said about it here except 

 to state that there is much confusion in the nomenclature of it. This confusion 

 seems to have arisen partly from the fact that the day lily grows readily from seeds, 

 and as the seedlings differ somewhat in time of blooming and also slightly in the 

 colour and size of the flower, when obtained from different sources, it may be found 

 after testing them that they vary considerably, suggesting different species, when in 

 reality they may be the same. The species cross readily, also, which has resulted in 

 hybrids, which also may have caused confusion. The day lilies succeed well in the 

 open border, but for best results they need moist soil and partial shade. They may be 

 propagated either from seeds or by division ; the latter is the ordinary method.
