The Apogon Section 79 
Of the cultivation of this Iris little need be said, except perhaps that the plant deserves better 
treatment in our gardens than is usually accorded to it. Though it grows most luxuriantly in the 
richest damp bog soil, it is still capable of producing a fine effect in any well enriched garden soil. 
Even in dry sandy soil, it will grow and flower, but, of course, mulching with old manure and leaf- 
soil are well repaid. 
No hybrids of this species appear to be known, but there seems no reason why crosses should 
not be successful with such a species, for instance, as /. versicolor , to which it has many affinities.
