being, as it is, in the superlative degree, would 
lead us to expect, in this Iris, a more brilliant yel- 
low than is shown by our plate; it is, however, 
closely copied from nature. It prefers a rather 
strong soil; is not of robust growth, nor does it 
increase so rapidly as many others. It is a free 
flowerer, and should have a place in every col- 
lection, although its flowers are not brilliantly 
coloured. 
In reference to the consideration of colours, we 
have usually found that the black soil of old gardens, 
similar to that in which this plant grew, rarely 
affords flowers with colour either so deep or bright 
as fresh earth of redder tint. The rich deep-col- 
oured wall flowers, sometimes called bleeding 
hearts, growing against a country cottage, may 
have met the admiration of many of our readers; 
and some may have proved that by transplanting 
them into town gardens, of black earth, they have 
become comparatively pale and ordinary coloured.
