PLANTS FOR WINDOW GARDENING. 



THTTNBERGIA. 



These pretty plants are usually grown as annuals with us, 

 for summer decoration in the flower garden, but they also 

 make fine window plants. For this purpose, sow the seed 

 in August in pots ; as the plants grow, transplant one to 

 each pot, and train the slender shoots on a neat trellis. 

 Give plenty of sun, and syringe very often, for the plants are 

 very subject to attacks "of red spider. They will show 

 bloom about the middle of January, and produce a profusion 

 during the winter arid spring months. The plants will show 

 bud very early, but if they are allowed to bloom, growth 

 will stop ; therefore it is best to pick off all the flower buds 

 until the plant is of the required size, when they may be 

 allowed to open. 



Cuttings root very freely in sand, under a bell glass. 

 The soil should be, one part turfy loam, one part peat, one 

 part well-rotted manure. Water moderately. 



The varieties are, — 



T. alata, buff yellow, with a black centre ; T. alata 

 aurantia, deep orange, with black centre ; T. alata alba, 

 white, with black centre. 



There are also some superb hot-house species.
