FLOWERING. IOI 



Lcelia majalis will keep four or five weeks, and Lalia 

 flava a long time. 



When it is probable that plants will come into blossom 

 earlier than is wished, the time of flowering may be suc- 

 cessfully retarded, by taking them to the cooler part of 

 the house or even to the greenhouse, keeping them 

 slightly shaded during the brightest part of the day. 

 Dendrobitims are very easy to keep back if they are 

 wanted later in the season. Dendrobium nobile, pulchel- 

 lum, macrophyllum, densiflorum, Farmerii, and Pierardii, 

 generally bloom in winter, but may be kept back till June, 

 and by having a succession of plants, the Orchid house 

 may be bright with Dendrobiums from January to June. 



All the Dendrobiums will bear cool treatment while at 

 rest, and all can be kept for late flowering. The treat- 

 ment they require in a warm greenhouse is to have but 

 little water, only enough to keep them from shriveling ; 

 the temperature should not go below 40 ; and the bulbs 

 of the plants must be kept dry or the flower buds are 

 apt to rot. When plants are wanted to flower, move 

 them into the Orchid house, and shade them from the 

 sun. Phajus Wallichii and grandifolius may be kept 

 back in the same way.
