As a special and important feature of water scenery the 

 exquisitely beautiful flowers of pond and stream should be 

 grown in suitable places. But they must never be allowed 

 to cover up the surface entirely or to form too thick and 

 crowded masses. Some of the finest of all flowers grow in 

 water or on lake and river shores ; the yellow flag and many 

 other forms of iris, the wild calla, the cardinal flower 

 (Lobelia cardinalis audfulgens), the water violet (Hottonia 

 palustris), and forget-me-not will grow on moist shores; 

 the many varieties of pond lilies, the lotus (Nelumbi'Wm

speciosum), the water poppy (Hydrocharis Humboldtii\ the 

 water crowfoot with its feathery and three-lobed leaves and 

 numerous white flowers, and the fragrant water hawthorn, 

 in more or less deep water. In lar^e ponds and lakes many 

 kinds may be established permanently, while the choicer 

 varieties should be planted in separate tubs and sunk to the 

 requisite depth near the shore. There is a subtle charm 

 about all water plants ; the lily resting on the bosom of a 

 lake, the golden flower-de-luce bathing its feet in limpid 

 water, and the blue-eyed forget-me-not all have been 

 loved and sung by a thousand poets.
