CARRYING OVER: WINTERING. 45 



hardy kinds as soon as ripe, but this is not absolutely necessary, but the best 

 results have been obtained in this way in some cases, particularly with Nym- 

 phsea pygmaea and N. gigantea; some of the same seed carried over to spring 

 failed to germinate. 



CARRYING OVER: WINTERING. 



Nymphseas of the stellata type, such as N. ciErulea, N. zanzibarensis, etc., 

 differ from other tropical kinds in that they do not send out side shoots, but are 

 mostly confined to one central crown, such plants are difficult to keep over 

 winter, as they will not make tubers, but will invariably rot if any attempt be 

 made to dry them off. Should it be desirable to save or retain a special plant 

 of this type for another season or otherwise, the plant should be lifted and 

 reduced in size (both leaves and roots), and planted in a tub or large pot, 

 placed in a tub or tank of water and kept thus growing on. The water need 

 not be above a temperature of 65°, and during cold weather the plant will not 

 suffer in a temperature of 60°, but in the former temperature the plant will 

 keep growing and produce some flowers all through winter. 



The tubers of all tender Nymphaeas may be kept in moist sand, or sandy 

 soil at a temperature between 50° and 60°; do not keep too dry, and at all times 

 look out for mice, as they will assuredly find out the tubers. All hardy 

 Nymphseas and Nelumbiums grown in tubs must necessarily be protected from 

 frost; this method of culture is not natural, hence the necessity of protection. 

 Our native Water Lilies in natural ponds have above them sufficient depth of 

 water to protect the roots so that they do not freeze. The tubs can be wintered 

 in a cellar, or plunged in the ground and covered with leaves, bracken, or 

 any material that will prevent them from freezing. Where such tubs of 

 Nymphasas are submerged in a tank, it is best to leave them in position pro- 

 vided the tank is frost proof, but it is best to protect the masonry, and the 

 whole tank where subjected to severe winter freezing. This may be effected by 

 covering with old lumber, leaves, branches, salt hay, etc., and where snow is 

 generally in plenty, any material that will collect and hold the snow should be 

 used, as there is no better protective material than snow.
