TREES AND SHRUBS.

shrubs succeed best in well-drained sandy loam and leaf-mould, 
and should be planted in early autumn. In winter the lateral 
shoots should be cut back fairly close. Increased by seeds 
sown in slight heat in spring, and by cuttings of the young 
shoots in summer in a cold frame. 
Jamesia. — The only species is J. americana, and this 
is a member of the Saxifrage order (Saxifragaceae), and a native 
of the Rocky Mountains. It grows 2 to 3ft. high, is deciduous, 
and bears white flowers in terminal cymes during early 
summer. An interesting dwarf shrub to grow in small beds 
or in groups on the margins of a sunny shrubbery. Plant in 
early autumn in good ,ordinary soil. Increased by cuttings of 
firm shoots in sandy soil in a cold frame in autumn ; or by 
seeds sown in similar soil in slight heat in March. 
Kalin ia. (American Laurel). — A genus of evergreen flower- 
ing shrubs, natives of N. America, and members of the Heath 
order (Ericaceae). They are very pretty and interesting shrubs 
requiring to be grown in moist sandy peat and leaf-mould free 
from lime. They do well to associate with hardy azaleas, 
rhododendrons, and other peat-loving shrubs. A partially 
shady position is desirable. In winter top-dress with well 
decayed manure, leaf-mould and peat. Plant in September or 
October. The best kinds are as follows : K. angustifolia, 
flowers purplish-crimson, June, 2 to 3ft. ; K. angustifolia 
glauca, lilac-purple, April, 2ft. ; K. latifolia, rosy-white, May 
to July, 3 to 6ft. ; K. latifolia myrtifolia, myrtle-like foliage. 
Increased by cuttings inserted in sandy peat in a cold frame in 
autumn, also by layering the shoots in October. 
Kerria (Jew’s Mallow). — Hardy deciduous flowering 
shrubs, natives of Japan, and members of the Rose order 
(Rosaceae). The typical species, K. japonica, grows 4ft. high 
or so, and bears single orange yellow rose-like blossoms in 
spring. It is not so desirable or beautiful as its double- 
flowered variety flore pleno, which has so long been a great 
favourite in English gardens. This bears large double rosette- 
like flowers on slender arching stems. The double variety 
is seen to the best advantage grown against a sunny shel- 
tered wall. The finest specimen we have ever seen grows 
against a wall at Kidderminster. The shoots are quite 10ft. 
high. There are two variegated varieties, K. japonica foliis 
argenteis variegatis, silvery-leaved ; and K. japonica foliis 
aureis variegatis, golden-leaved. Plant in autumn in good 
ordinary garden soil. Every year, directly the plants have 
flowered, cut out the old wood. Increased by cuttings of the 
young shoots in sandy soil in a cold frame in summer; division 
of the roots in autumn.
