104 PLANT PROPAGATION 
the warm, moist atmosphere of a_ propagating-case. 
When united they may be gradually hardened off until 
fit to plunge in a bed of ashes outside. Layering also 
succeeds if young shoots are put down in summer and 
covered with soil until rooted sufficiently to be severed 
from the parent. Cuttings of young shoots will strike 
in gentle heat in a propagating-case, and seeds can also 
be raised when procurable. . The herbaceous kinds are 
increased by division and seed. 
CLERODENDRON.——-The methods of increase are by 
cuttings of ripened wood and side-shoots, root-cuttings, 
and seed. C. fallax, sown in April in heat and grown 
on without check, will produce large heads of scarlet 
blossoms in autumn; root-cuttings will also grow 
readily. The hardy Japanese C. trichotomum can be 
rapidly increased early in spring by fleshy root-cuttings, 
3 or 4 inches long, dibbled upright (tops uppermost) in 
sandy compost, with the tops just covered, and placed 
' in a cold frame. 
CiiantHus.—The Glory Pea of Australia, C. Dam- 
pieri, can be easily raised from seed, but the plants are 
very fastidious; they sometimes grow with vigour, 
appear robust and healthy one day, and the next, for 
some unknown reason,. will be in a pitiful, drooping 
state, from which they never recover. Very healthy and 
beautiful specimens have been obtained by grafting on 
young seedling stocks of Colutea arborescens (Bladder 
Senna). Seeds of the Golutea are sown singly in small 
pots in spring. Three weeks later seed of C. Dampieri 
are sown, and when the first true leaf appears they are 
in the right stage for scions, which are side-grafted and 
tied tenderly with raffia. They are then placed in gentle 
bottom heat in the propagating-house and covered with
