THE FLOWER GROWER'S GUIDE. 



lings singly when 3 inches high. When well established either shift into larger sizes 

 or plant them in a narrow border. Old plants may be divided when on the point of 

 growing in the spring ; take care to save some roots with each division, and establish 

 them in pots, subsequently shifting into larger pots, or plant out. Compost suitable : 

 equal parts of fibrous loam, peat, and leaf soil, with abundance of sharp sand to ensure 

 porosity. 



boronia. — These rank among the most elegant hard- wooded plants in cultivation,

 U/y f 'I I I '' cultivated. B. Drummondi (New Hol- 



X j ' - land), height 2 feet, flowers rosy pink, 



"^f^TO JlS^ i\i'JWi3lJ^ abundant in spring and summer; B. elatior 



(Western Australia), height 4 feet, flowers 

 in dense clusters along the ends of the 

 branches, rosy carmine, fragrant, May ; 

 B. megastigma (Western Australia), height 

 1 foot, slender and twiggy, flowers maroon 

 purple, yellow inside, deliciously fragrant ; 

 B. serrulata (Port Jackson), height 1 to 5 

 feet, flowers deep rose, sweet-scented, July; 

 and B. tetrandra (New Holland), height 

 1 to 4 feet, flowers pale purple and pro- 

 duced singly, May, are the best of the 

 species. Propagation is effected by cut- 

 tings of firm young shoots during the 

 summer, inserted in pans or heavily-drained 

 pots filled with sandy soil, in a greenhouse 

 or temperature of about 55°, covered with 

 a bell glass and shaded. The bell glass should be dried every morning as a safeguard 

 against the cuttings damping, and water must be applied carefully round the rim of 

 the pot, without disturbing the glass. When rooted, the young plants ought to be 

 placed singly in very small pots and plunged in cocoa-nut-fibre refuse or other material 

 free from worms. Frame culture answers well for these small plants during the fol- 

 lowing summer, and they must be topped frequently to lay the foundation of neat 

 bushes. Give a small shift as required, using a compost of equal parts of light fibrous
