ponds or basins. They can also be grown in tubs with 

 good success, but the roots must be wintered in a green- 

 house-tank or be purchased at the beginning of every season. 

 If considerable skill is exercised by covering the plants with 

 barrels, then with leaves and straw, they may be carried 

 over winter in the tank or pond. 



They may be divided into two groups: i.e., first, those 

 blooming during the day, opening m the morning and 

 closing at night; and second, those opening in the evening, 

 remaining open during the night and until toward noon 

 the following day. 



The best of the DAY-BLOOMING varieties are: PURPLE 

 ZANZIBAR OR AFRICAN LILY (Nymphoea Zanzibarensis) , 

 ROYAL PURPLE AFRICAN LILY (N. Z. var. azurea), SUPERB 

 AFRICAN LILY (N. Z. superba). These species may 

 be had in bloom constantly from July to September, 

 if planted in rich soil in shallow, warm water in ponds, 

 basins, or tubs. For the best results in tubs they should 

 be placed on the south, southeast, or southwest shelter of 

 buildings or shrubbery, where the sun will strike them for 

 6 to 8 hours per day. A bright, sunny exposure is also 

 desirable for the location of the pond or tank, that the 

 water may be kept as warm as possible. 



The best varieties o the NIGHT-BLOOMERS are : The 

 DEVONIAN WATER-LILY (Nymphcea Devoniensis), one of 

 the choicest and most beautiful, with bright rose-colored 

 flowers and scarlet stamens. EAST INDIAN WATER-LILY 

 (N. rubra). WHITE AFRICAN WATER-LILY (N. dentata), 

 one of the most free bloomers, with flowers of large size and 

 very easily grown. ROYAL WATER-LILY (Victoria regia), 

 the largest of all the water-lilies, its leaves often measuring 

 4 feet across and the flowers a foot in diameter. Very 

 few persons succeed in blooming this royal flower, and then 

 it is done only where artificial heat is introduced from some
