COOL GREENHOUSE, 107 



CHAPTEE III. 



COOL GREENHOUSE. 



IN this section such bulbous and tuberous-rooted plants as 

 require only a little artificial heat in autumn, winter, and 

 spring will be dealt with. The average night temperature 

 should be 40 to 45 deg., or 50 to 55 deg. by day. These 

 temperatures refer to artificial heat. On sunny days the 

 temperature may, of course, go higher. A greenhouse of 

 this character is a pretty general feature in small gardens. 

 In summer no artificial heat will be required. 



Anoiganthus. A. breviflorus, the only species, is 

 a South African bulbous plant, bearing yellow flowers in 

 May. It is an interesting plant to grow by those who 

 are fond of uncommon bulbs. 



The bulbs require to be grown four or five in 5in. pots, 

 in a compost of two parts loam, one part leaf-mould, and 

 plenty of coarse silver sand. Plant the bulbs two inches 

 deep. After potting, place in a cool corner qf the green- 

 house, and give no water till growth begins; then apply 

 cautiously as it proceeds, watering more freely later on. 

 The plants will do best on a sunny shelf until the flowers 

 appear, After flowering, gradually withhold water, and 

 keep dry all winter. Eepot in March, and start to grow 

 as before. Increased by offsets. 



Antholyza. South African bulbous-rooted plants of 

 easy culture, and very pretty when in flower. 



Plant half a dozen bulbs two inches deep in a 6in. pot 

 in October, using a compost of equal proportions of loam, 

 peat, leaf -mould, and coarse silver sand. Store in a cool 

 part of the greenhouse, and give no water till growth 

 begins. When the latter occurs place in a light position and
