THE FLOWER GARDEN. 
rich yellow tint in autumn. This makes a handsome lawn 
tree. Native of N. America. C. amurensis is a native of the 
Amoor Valley, grows 6 to 8ft. high, and bears whitish-yellow 
flowers in dense spikes late in summer. Both do best in well- 
drained sandy loamy soils. Plant in autumn. Increased by 
seeds sown in sandy loam outdoors, also by root cuttings 
planted in spring outdoors. 
Clerodendrort. — Two species of this genus of flower- 
ing shrubs are cultivated outdoors in mild parts of the king- 
dom. Both are deciduous and belong to the Verbena family 
(Verbenaceae). C. foetidum (Syn. C. Bungei) is a native of 
China, grow's about 5ft. high, has heart-shaped leaves, and 
bears lilac flowers in August. We have seen it grow ing almost 
wild in a farmhouse garden at Buxted, in Sussex. It does well 
in sheltered gardens in the South. C. trichotomum is a native 
of Japan, grows 8 to 12ft. high, and bears white fragrant 
flowers late in summer. This species also requires a shel- 
tered position and a sandy loamy soil liberally mixed with 
leaf-mould. Plant in autumn or spring. Increased by seeds 
sown in light soil in heat in spring, and the seedlings after- 
wards grown on for a year before planting out ; cuttings of 
young shoots in spring in heat ; suckers, removed in autumn ; 
also by layering shoots in sum®er. 
Clethra (Sweet Pepper Bush). — Hardy deciduous flower- 
ing shrubs, members of the Heath order (Ericaceae), and 
adapted only for growing in boggy or peaty soils. C. alni- 
folia is a North American species, growing 3 to 6ft. high, 
with alder-like foliage and white fragrant flowers borne in 
feathery spikes in July and onwards. It is largely grown for 
forcing in hot-houses in winter. C. arborea is a native of 
Madeira, grow's 8 to 10ft. high, and bears white flowers in 
August. C. canescens is a new hardy white-flow T ered species 
from Japan. The flowers are borne in panicles over a foot 
long. A most desirable species. All the foregoing should 
be grown in bog or peat and leaf-mould in moist, sheltered 
positions. Plant in autumn. Increased by seeds sown in 
peaty soil in a cold frame in spring ; cuttings of ripened wood 
with a heel attached in a similar soil and position in autumn ; 
layers in summer. 
Colletia. — Evergreen shrubs, natives of Chili, and mem- 
bers of the Buckthorn order (Rhamnaceae). These shrubs are 
very spiny, and on that account are only adapted for the 
shrubbery or hedges. They are not hardy enough to succeed 
outdoors except in the South and West of England. C. cruciata 
is a bushy species, about 4 to 5ft. high, and C, spinosa grows
