166 WALL AND WATER GARDEN 



The foregoing are all of vigorous and dense growth, 

 being seen to the best advantage in deep water when 

 well established, say from four to eight feet. 



The Laydekeri section of the Marliac Water-Lilies 

 appears to have some affinity with N. odorata in the 

 form of their flowers, but the root-stock is quite 

 different ; possibly this resemblance was subdued in 

 one of the parents. Of these hybrids N. Laydekeri 

 rosea is extremely difficult to propagate ; it is not 

 disposed to make offsets, hence it is only increased 

 by seeding. These are well suited to shallow pools 

 of water, and for fountains, tanks, or tubs. 



Nymphaa Laydekeri rosea, a pale rose colour, darken- 

 ing each day with age ; three colours are 

 frequently seen upon the same plant ; 

 comes into flower quite early. 



Laydekeri lilacina, different, in that it propa- 

 gates freely ; flowers tinged with pale 

 lilac. 



Laydekeri purpurata, a darker form of the 

 foregoing, otherwise similar. 



Laydekeri fulgens, the darkest of this section, 

 and larger in size of flowers and in 

 growth. 



Laydekeri rosea prolifera is reputed to be 

 true to its name. 



The N. odorata section of the Marliacean hybrids 

 have a greater resemblance to their parent on this
