lOO WATER-LILIES 



from one to two feet above the root-stocks; but 

 N. odorata and N. tuherosa, it is true, will 

 stand three or four feet. But for depths of 

 two to five feet N. alba, var. candidtsstma 

 is recommended. Large plants of this will 

 make a wide spread of lo-inch leaves, 

 and will produce splendid white flowers from 

 the first of June until frost. This is one of 

 the earliest bloomers in spring. It is exceed- 

 ingly strong and hardy. 



For depths of water up to eight or ten feet 

 the giant Southern pond-lily {N . odorata, 

 var. gigantea) is best. It is little more than 

 a large odorata. The leaves reach a foot or 

 more in diameter, the flowers four or five 

 inches. 



The following table will aid in identifying 

 any of the hardy kinds.
