C. pyramida'lis continued. 



drawn. It also makes a lovely plant for the 

 conservatory. Bamboo stakes to support it 

 are necessary when it gets very tall. There is 

 a pure white variety equally attractive. 



C. sibi'rica is a dwarf biennial plant, about 12 ins. 

 high, having pale violet flowers, with the habit 

 of C. me'dium. Siberia, 1783. 



C. speculum. See SPECULARIA speculum. 



C. thyrsoi'dea. A biennial of quite distinct form. 

 Yellowish flowers in a dense head. Height 

 1J ft. Switzerland, 1785. 



Propagate the annual species by sowing the 

 seed outdoors iV in. deep in March or April in a 

 warm border, and thinning out, though C. macro- 

 styla is better started in warmth during March and 

 hardened off and not planted out till June. 



The biennials should be sown in June or July 

 in the open, and thinned out to 12 ins. apart, or 

 else in boxes and dibbled out when large enough 

 to handle. In the autumn or late summer these 

 will be ready to plant out where they are to grow, 

 allowing 2 ft. apart in the case of C. pyramidalis, 

 or potted up if intended for the conservatory in 

 good-sized pots. Campanulas all like a light rich 

 soil, and should never feel the want of water.
