By having the edge of the pond lower than the earth around it, 

 many semi-aquatic plants may be grown in the resulting mud. 

 The most striking of the hardy ones are : 



Arundo donax. 



" " oar. 



' Eulalia Japonica. 

 Zizania aquatica (wild rice, will also grow in water). 



But a catalogue of aquatic and semi-aquatic plants will furnish 

 all the information necessary in selecting plants. 



All ponds ferment and are very disappointing in the early 

 summer, but during August and September they are fine. 



In many ponds the plants stop blooming from lack of room ; 

 they become crowded towards the end of August. Watch them 

 and throw out some of the surplus plants before this happens. 



But these are only a few of the possibilities of a lily pond. If 

 a natural pond is used the bottom should be prepared as described, 

 or boxes be used to hold the lily roots. 



The various Nelumbium (lotus) varieties may also be groAvn in 

 the same way as lilies.
