64 THE UNHEATED GREENHOUSE 



a window in a warm room will answer perfectly, as it also 

 does for the better known Scarborough Lily (Vallota purpurea). 

 Belladonna Lilies, on the other hand, will so rarely flower 

 in pots that they cannot be recommended for the smaller sort 

 of unheated greenhouse, but planted out in rather poor 

 gravelly soil, they are admirable for the narrow borders close 

 to the wall which are found in some conservatories and 

 corridors. 



For such positions also though it also flowers very well in 

 pots the handsome Crinum Moorei is very suitable, especially 

 when associated with such plants as Funkia Sieboldi and F. 

 grandiflora (good both in foliage and flower) which will serve 

 to hide the somewhat ungainly length of stem of the Crinum. 

 A note should also be made of another Funkia recently 

 introduced F. lancifolia tardiflora which on account of its 

 late flowering should prove valuable under glass. 



Kniphofias the Red-hot Pokers of our gardens may not 

 seem exactly suitable to rank as pot plants, yet there are 

 some species which do well and are extremely useful grown 

 in this way for autumn flowering. The very dwarf K. 

 Macowani and the more robust K. corallina are kinds in 

 point. For these a cold frame with sunny exposure is the most 

 suitable position in order that the flower scapes may attain 

 their full rich colour. The new taller growing species, K. 

 longicollis, though hardy, produces its clear yellow flowers too 

 late to open well out of doors, but succeeds admirably planted 

 out under glass, where there is space for it. It would be 

 worth trying, when it becomes better known, grown in a 

 pail or tub for smaller structures where only pot plants can be 

 accommodated, as it flowers naturally from late autumn 

 onwards into winter. 



The new Anoiganthus breviflorus, which opens its umbel 

 of golden-yellow flowers in December, may also find a place 

 in the greenhouse with temporary warming power. But
