80 PLANT PROPAGATION 
be sown in a moist soil in March. Increase is also 
effected by suckers and cuttings. Many of the choice 
kinds are grafted on stocks of the Common Alder. 
ALOCASIAS are propagated by division of the rhizomes 
in March, using a compost of fibrous peat and silver 
sand and placing the pots in a bottom heat of 75 degrees. 
_ ALoeE.—Plants of this extensive family of succulents 
are chiefly propagated by the suckers that spring up 
from the roots, and occasionally by seeds sown in pots 
of sandy soil. 
Atonsoa.—-The annual kinds are raised from seed 
sown in March; the perennials by cuttings of young 
shoots in a propagating-frame. 
ALSTREMERIA.—Divide the roots in spring or sow 
seed in deep pans placed in a cold frame or pit, the 
resulting seedlings being replanted in flowering positions 
the following season. 
ALTERNANTHERA.—Cuttings of these strike readily in 
spring in a temperature of 75 degrees with bottom heat 
if taken from old plants that have been encouraged to 
sprout by increased heat and moisture. 
ALyssuM.—Sweet Alyssum may be sown out of doors 
in spring or ina frame. A. saxatile compactum may be 
raised from young cuttings inserted in sandy soil on a 
shaded border, and many of the alpine species, by 
division of the roots. 
AMARANTUS.—The hardier sorts may be sown out of 
doors in April. The half-hardy kinds do well if sown on 
a gentle hotbed with protection from cold, to provide 
material for planting out late in May or early in 
June. 
AMARYLLIS, such as the Belladonna Lily, increase by 
offsets which may be taken off in June and planted in a
