October Looking Forward 



treatment is necessary, and, whenever the weather allows 

 of it, air should be freely admitted to counteract the 

 dampness of the atmosphere. 



Various plants are much hardier than they are 

 generally thought to be. In a cold greenhouse I have 

 grown the dainty lilac-coloured Primula malacoides, the 

 golden yellow Primula Kewensis, Calceolaria, Cineraria, 

 Persian Cyclamen, Chinese Primula, and even a Lady's 

 Slipper Orchid, Cypripedium insigne. Geranium and 

 Calceolaria cuttings take no harm there, and roots of 

 Tuberous Begonias may be stored in pots of sand or soil. 

 I have kept all these flowers throughout the winter 

 despite the fact that as much as 5 of frost has been 

 registered in the greenhouse. The item of chief impor- 

 tance is to keep the atmosphere as dry as possible, and 

 to give no more water than is absolutely necessary. 

 Although it is interesting to experiment with such flowers 

 as are named above, the hardy kinds are really most suit- 

 able for the unheated greenhouse. Roses are especially 

 valuable, whether in pots or planted out, while such 

 hardy annuals as Snapdragon (this is really a perennial, 

 though best grown as an annual), Clarkia, Godetia, Stocks, 

 etc., are showy in spring and quite easy to grow. 



Roses in Pots. It is very delightful to be able to 

 gather Roses from a greenhouse in April and May, and 

 it is not a difficult matter to do so. No artificial warmth 

 is necessary ; an unheated greenhouse is suitable. With 

 the longer days and 'increased sunshine of late March 

 and April the temperature of the greenhouse rises rapidly, 

 and if the ventilators are closed early in the afternoon 

 the atmosphere remains warm throughout the night. 

 Many amateurs fail with Roses because they attempt 

 to grow them in a high temperature before they are well 

 established in pots, with the object of obtaining bloom 

 in early spring. Roses potted up now should not be 

 forced next spring ; if this is attempted not only will the 

 plants be weakened but the blooms produced will be of
