MASSING OF DISTINCT SPECIES 163 
Crimean irises. Then the Intermediate, a 
cross between the German iris and olbiensis , 
not so tall as the German iris and flowering 
two or three weeks earlier, many sweet-scented, 
and all specially suitable for massing and broad 
effects. 
The German iris, to which belongs the old 
Blue Flag well known to all, flowers in May and 
June, and includes the handsomest and easiest 
grown of all the iris family. They, together 
with all the rhizomatous or creeping-rooted 
iris, grow rather on the top of the ground, 
especially in damp soil, certainly only just 
below the surface. They appreciate a good 
mulching of old cow manure over their roots 
in March, also waterings of weak liquid 
manure during the summer. 
They may be moved, like many another 
good thing, in full bloom if given plenty of 
water overnight, and if carefully lifted without 
disturbing the roots, and are increased by 
dividing not later than August or September. 
Some say even earlier, if they can be well 
watered. 
Under the various sections of Amoena, 
Aphylla, Neglecta, Pallida, Squalens, and 
Variegata are to be found the most beautiful 
and best known of them all.
