258 THE NURSERY-MANUAL 



Bougainvillea. Nyctaginacece. 



Handled by cuttings from the half-ripened wood from April to 

 June ; place in sandy soil in bottom heat ; keep moist at tempera- 

 ture 65 to 70. Also grown from root-cuttings. 



Boussingaultia (Madeira Vine). Bassellaceae. 



Propagated by seeds, and easily by means of the tubercles on 

 the stem; also by the underground tubers. 



Bouvardia. Rubiaceoe. 



Commonly propagated by root-cuttings, which strike readily ; 

 the larger and thicker roots are taken in spring for this purpose. 

 Cuttings of shoots are also used, struck in heat ; these cuttings are 

 made of fresh shoots arising from plants cut back after bloom and 

 kept at comparative rest for a time. The cuttings should be 2 

 inches long and taken with a heel, and placed in pots in brisk bottom 

 heat ; it is best to put the pots in a propagating-frame till roots 

 form. 



Bowiea. Liliacece. 



Propagated by seeds, or offsets from the great bulbs. The name 

 of this remarkable plant is now Schizobasopsis wlubilis, rather than 

 Bowiea wlubilis. 



Brachycome (Swan River Daisy). Composites. 



Multiplied by seeds in early spring, and transplanted ; or they 

 may be sown thinly outdoors, late in spring in regions of long 

 seasons. Easily grown. 



Brahea. Palmacece. 



Grown from seeds in heat. See Palms, page 377. 



Bramble Fruits: Blackberry, Dewberry, Loganberry, Raspberry, 

 Wineberry. 



Brassavola. Orchidacece. 



Increased by division. See Orchids, page 372. 



Brassia. Orchidacece. 



Propagated by dividing the plant when growth begins. See 

 Orchids, page 372. 



Brassica: Brussels Sprouts, Cabbage, Cauliflower, Collards, Kale, 

 Kohlrabi, Turnip. All readily grown from seeds ; hardy.
