inus Laricio (Corsican Pine, or Black Pine). As indifferent to exposure
as P. austriaca, P. montana (dwarf), and P. sylvestris (Scotch Fir),
a well-known native, which often crowns high hill-tops.

Populus alba (Abele), P. fastigiata (Lombardy Poplar), P. deltoidea
(Canadian Poplar), P. nigra (Black Poplar), and P. tremula (Aspen).
In low-lying districts all these Poplars are of rapid growth, but in
exposed places they make much slower progress. Even then they grow
quicker than most shelter plants, and are valuable for making an
effective display more quickly than some of the more permanent
subjects. These can all be readily cut back within reasonable limits
if desired.

Quercus Robur (Oak).

Robinia Pseudacacia. The false Acacia is one of the best town trees we
have; indeed, it does well almost everywhere.

Salix alba (White Willow). This will pass unscathed through fierce
storms. In fairly dry spots the rate of progress is much slower than
in moister soil, but, as a set-off, the silvery hue of the foliage
is more pronounced.

Ulmus (Elm). The best of the Elms for this purpose is the Wych Elm, and
one known as the Wheatley is also good.

SHRUBS

Atriplex Halimus (Sea Purslane). A silvery-leaved, free-growing shrub,
indifferent to soil or situation.

Berberis (the Barberry). The best of these are the strong-growing
Berberis aristata, and the common Berberis vulgaris, with its
several varieties.

Colutea arborescens (Bladder Senna). The golden flowers in early summer
and the large inflated seed-pods in autumn are both attractive.

Cotoneaster buxifolia, Nummularia, and Simonsii. These are all pretty
berry-bearing shrubs.

Cytisus albus (White Broom), Cytisus scoparius (Yellow Broom), and its
varieties.

Deutzia crenata flore-pleno. A handsome flowering shrub and the most
robust of its class.

Euonymus europaeus (Spindle tree). The fruits of this are very
ornamental in the autumn.

Halimodendron argenteum (Siberian Salt Bush). A pretty rambling shrub,
with silvery leaves.

Juniperus communis and J. Sabina (Savin). The fact that these Junipers
are evergreen is a point in their favour.

Ligustrum ovalifolium, ovalifolium elegantissimum, and vulgare. These
Privets are well known for planting where the conditions are none
too fa
