I 86 GARDEN PLANNING 



space permits, including such interesting sub- 

 jects as the pickerel weed, the flowering rush, 

 and water buttercup. Typha and swamp mal- 

 low might be planted along the fence line 

 at B. 



Irises will thrive at the margin of the water, 

 as well as such favourite flowers as phlox, 

 trollius, spirea, and a host of others. With very 

 little trouble in the making and common-sense 

 management, a piece of water of this kind could 

 be made a source of perennial interest. When all 

 is complete and the plants are established it 

 would only remain to keep the entrances clear 

 and to remove all rubbish which might find 

 access to the water. No deciduous trees or 

 shrubs should be placed near the water, for 

 reasons already explained. 



A water system of this kind might be wedded 

 to a rock garden with a good effect. 



In excavating the water bed the sides should 

 slope gently to the edge, or trouble will ensue 

 by the banks breaking away and fouling the 

 water. This also ensures that the soil is water- 

 logged for some distance from the water's 

 edge, and is therefore in a condition for sup- 

 porting a colony of semi-aquatic plants.
