American Mountain Ash is a good street tree, in autumn loaded with its
handsome bunches of scarlet fruit.

The larger Willows are also charming trees for streets. Many of the
trees named, if their tops spread too near the houses, may, with good
effect, be pollarded about 10 feet from the ground.

TREES AND SHRUBS IN SCOTLAND

The following list has been kindly sent me by a great lover of trees and
shrubs who lives at Forres. My correspondent writes: "I have grown all
the plants in my list in my own garden, except _Buddleia globosa_ and
_Aralia chinensis_, but the latter is grown in quantity by several of my
neighbours, and there are also several fine plants of the Buddleia in
many gardens in sheltered spots. My experience is that many plants are
quite frost-proof but cannot stand cold winds. This applies more
especially to the shrubby Veronicas. I have seen them in the Edinburgh
Botanic Gardens as if scorched with fire on the exposed side, while they
were untouched where sheltered from the north and east. My own garden is
fairly well sheltered."

_Amelanchier canadensis._--Hardy, free-flowering, beautiful at all
times.

_Aralia chinensis (Dimorphanthus) mandschurica._--Useful in some
positions for its curious habit of growth and rather handsome foliage;
quite hardy.

_Aristolochia Sipho._--This has curious and inconspicuous flowers, which
give this climbing plant its popular name of "Dutchman's Pipe." It can
be grown on a wall, in which position, perhaps, its fine foliage is
seen to the best advantage, but it is quite hardy and looks well
climbing into a thin tree such as the Common Almond.

_Berberis (Mahonia) Aquifolium._--A handsome plant at all times, and
will even grow under the shade of trees.

_Berberis Darwinii._--Very bright in flower. Young and sappy shoots get
killed back in winter.

_Berberis Thunbergi._--A most attractive Berberis; it makes a small
neat-growing bush to which the adjective "sparkling" might be applied.
Its chief glory is its autumnal foliage, and a large clump in September
is "a sight to see"; quite hardy.

_Berberis vulgaris._--Very beautiful when clustered with fruit. The
purple-leaved variety (_B. v. purpurea_) is most useful for its foliage.

_Betula alba purpurea._--A good foliage tree.

_Buddleia globosa._--This does well in a warm sheltered spot facing
south-west, where the morning sun in winter will not touch it too soon.
