LIST OF PLANTS gI 
in small pots in February, but more generally by striking 
cuttings of the young shoots when the old plants start 
into growth. The variety called John Heal (named after 
the raiser, who has enriched our gardens with many 
excellent hybrid flowers), Gloire de Lorraine, and many 
others belonging to this section, are highly valued for 
producing abundant blossoms at a season when such are 
much appreciated. 
B. semperflorens.—If seed of these be sown in heat in 
February and the resulting seedlings grown on in a 
congenial temperature, they will supply suitable plants 
for planting out in June. 
B. manicata, a favourite old Mexican species, and 
others of similar habit, are easily propagated by offsets 
from the rhizomatous stem. 
BERBERIS.—These ornamental flowering and _ berry- 
bearing plants can be raised from seed cleaned from the 
pulp and sown in autumn, or from that which has been 
stratified in moist sand through the winter and sown in 
spring. Other methods are by suckers, by layers put 
down in October, and by cuttings of ripened shoots 
inserted in a cold frame in September. | 
BIENNIALS are successfully treated by sowing hardy 
kinds in July or August for flowering the following 
season. Some perennials that flower most profusely 
the second year from seed, such as Foxgloves, Sweet 
Williams, and Wallflowers, are commonly given the 
treatment of biennials. 
Bicnonia.—These handsome flowering climbing plants 
are propagated by firm cuttings of the side-shoots, about 
3 inches long, inserted in pots of sandy compost in the 
propagating-case or under a bell-glass with a tempera- 
ture of 70 degrees. The glasses should be wiped each
