TREES AND SHRUBS. 
405 
graceful shoots in August. In general appearance this shrub 
is much like a species of broom, and it belongs to the same 
order (Leguminosae)* A native of New Zealand. It will thrive 
in good ordinary soil in a sunny sheltered border. Probably 
not hardy enough for northern gardens. Plant in May or 
September. The only pruning required will be a thinning 
out of weak wood in winter. Increased by seeds sown in 
sandy soil in a cold frame in spring ; also by cuttings of 
shoots inserted in sandy soil in a cold frame in autumn. 
Nuttall ia (Oso Berry). — The only species of this genus 
is N. cerasiformis. This is a hardy deciduous flowering shrub 
from California, which grows 6 to ioft. high, and bears small 
white flowers in drooping racemes on the leafless shoots early 
in the year. It belongs to the Rose family (Rosaceae). This 
shrub is quite hardy, and will grow in any good ordinary soil 
in the mixed shrubbery. It will do well even on a poor 
gravelly soil. Plant in autumn. No pruning beyond thinning 
out dead wood or shortening a branch here and there is 
required. Increased by cuttings of ripened shoots in a cold 
frame in autumn ; layering at same time ; or by suckers. 
Olearia. (Daisy Tree). — Hardy evergreen flowering 
shrubs, belonging to the Daisy order (Composite). They are 
mostly of dwarf growth, and form neat bushes, thus rendering 
them specially suitable for small or gardens. One of the best 
species is O. Haastii. This grows 2 to 4ft. high, has box-like 
leaves, hoary beneath, and bears a profusion of aster-like 
flowers in August. A really good shrub to grow in small front 
,gardens, singly on the lawn, or in front of a mixed shrubbery. 
Other species are O. macrodonta and O. stellulata, nitida, etc. 
These, however, are not quite hardy, and may only be grown 
against warm walls in mild districts. Plant in May or Sep- 
tember in good ordinary soil. No pruning needed. Increased 
by cuttings inserted in sandy soil in a cold frame in Septem- 
ber ; also by seeds sown in a similar soil and position in 
autumn or spring. 
Oxycoccus (Cranberry).— The native Cranberry of our 
moors and bogs (C. palustris) is an interesting dwarf, trail- 
ing shrub to grow in a bog or other moist spot in the 
garden. Apart from its pink flowers, borne in May, it bears 
red berries later on, which are edible. The American Cran- 
berry (O. macrocarpum) bears larger berries than the common 
species. Plant in autumn. Increased by layering in autumn, 
also by seeds sown in moist peat outdoors. 
Oxydendrum (Sorrel Tree). — O. arboreum is a hardy 
evergreen flowering shrub or tree from the United States.
