THE WATER-GARDEN 275 
~ 
With a pool of two feet depth any one may hope in rich 
deep soil to have blooming beds of Calla ethiopica, per- 
fectly hardy as the plant is—or rather becomes, if its 
roots are planted in water beyond reach of any but an 
extraordinary frost. 
In the south and west of England indeed the Calla has 
become a water-weed, blooming by the acre; and there 
is no sort of reason why, in any fairly clement part of 
England, the same gorgeous result could not be achieved. 
But the Calla must be planted ina broad sweep, and I have 
not had space enough so far to deal with it massively by 
the hundred yards. As an isolated crown I flowered it 
well and enjoyed it for several seasons in my old pond. 
But this was so ridiculously shallow that it froze solid and 
cracked every winter. After three such experiences the 
Calla grew peevish and expired. Now, however, that I 
am restoring the pool on a proper scale, I shall renew 
my experiments with the Arum, and hope for finer and 
more permanent results, even though my pond is not 
large enough for it to be used as freely as it should, to 
gain its full effect. 
Two other important plants are Aponogeton and Buto- 
mus umbellatus. 'The Flowering Rush loves shallow, 
sluggish water, and is found by streams and canals all 
England over—in appearance a big lax-leaved rush, until 
you see, on tall stems, its flattened heads of large pale pink 
flowers. This flourishes in any water not too deep, and 
its only drawback is its tendency to become a weed. A 
fortiori the same applies to the giant Bulrush, magnificent 
as it is, and to pretty, fluffy-balled Sparganium ramosum, 
and to the great Dock, one of the handsomest of foliage 
plants, no matter what exotic rivals you may adduce. 
Much slenderer, and safe to admit, though, is Typha minor. 
The lesser Bulrush is far slighter and more graceful than 
its major—a fine gracious thing, sufficiently rampant in
