Planting the Garden Feature
The planting around the principal garden feature must be
different from that of the shrub border used for enclosure.
The feature requires richer material, usually some ever
greens, both conifers-pines, firs, and spruces-and hollies.
These are too exotic and expensive for general use throughout
the border, but they give the finish needed to accentuate the
focal point. This is also the place for colorful azaleas and
hybrid rhododendrons, which here will not have to compete
with herbaceous material in front or rampant shrubs behind.
At the sides or among the larger evergreens, sourwood, fringe
tree, cercis, and flowering dogwood give both bulk and light
ness. A tall cedar, an arborvitae, or even a Lombard poplar
way at the back, just off axis, will focalize the whole picture.

Hedges
Where privacy must be achieved and there is insufficient
room for a shrub border, or where definite clipped lines are
important to the design, use hedges. Usually they are less ex
pensive than shrub borders, and always less than masonry
walls or fences. On the other hand a hedge, if it is to look
well, is more trouble to maintain than any other garden en
closure.
The type of hedge depends on the degree of formality of
the garden. Hedges can be either informal or formal, or any
thing between. Try to choose a hedge with a clear idea of
what final effect you want. If you are after a sharp trim look,
choose one of the few suitable plants, like Hicks yew. It stands
continual close clipping. If you can be content with a less
rigid line, your choice is wider. Almost any shrub or small
tree planted in a straight line at regular intervals will pro
duce a hedge, but for a trimmed hedge, avoid forsythia, flow
ering quince, or spirea whose flowers are borne close to the
branches or in terminal clusters. All grace and charm is lost
when they are clipped. Other shrubs, whose flowers are un
important, like the viburnums, may be clipped quite closely.
Although the flowers are lost, the hedge is attractive nonethe
less.
Most people, when you say hedge, think of California
privet or Japanese barberry, both good but overused. Subur
ban landscapes would be improved if an embargo were de
clared on these two for ten years. The ibota and Amur privets
are hardier than California privet, and also adapted to clip
ping. Among the evergreens, hemlock, upright yew, arbor
vitae, and Japanese holly are the best. Stephanadra flexuosa
(hardy south of New York), Viburnum prunifolium and den
tatum, Euonymous alatus and its dwarf relative compacta,
Lonicera tatarica and morrowi, beech, hawthorn, and horn
beam, all make good deciduous hedges either closely clipped
or slightly restrained. Regels privet is particularly fine, if
only slightly restrained by the cutting back of overlong
branches. It will reach a height of eight to ten feet, and can
then be cut back to a foot or so, and allowed to start all over
again. Such treatment creates a more graceful hedge than
constant shearing or clipping.
