Hedges have been a part of landscapes for centuries. Whether planted for privacy screens or for ornamental value, there are lots of plants to choose from.

What is the purpose of hedging?

Hedges can be tall windbreaks of conifers striding across the skyline, the green stuff between your house and the road or a neat, step-over edging to a path. Whatever form it takes, a well-grown hedge adds cohesion to a garden and also solves design problems by providing shelter, privacy and uniformity.

The simplest hedge is a row of closely planted, dense shrubs that create a green wall either along a boundary or within a garden. However, there are many other hedges that can be grown and they can become an important part of your property.

Hedges up to 3 feet

Hedges at this height create a softer visual barrier between properties while blending in with multiple landscape schemes. These low hedges can mark the boundary of your property without losing much space or reducing light the way traditional hedging can. This low hedging can also be used as a feature within other plantings or as a feature against walls or fencing.

Consider these plants for maintaining up to a 3 foot hedge (pruning will maintain the height you want)

Don’t forget ornamental grasses

There are many varieties of ornamental grasses to choose from. Several of these grasses grow to be up to 12 feet in height, making them perfect for privacy. Grasses are excellent noise barriers as well and have attractive blooms that persist well into the winter months for aesthetic appeal. In the breeze, grasses add movement and sound to the garden.

Consider a Hedgerow

A hedgerow is a mix of deciduous and evergreens of various sizes that, combined, will contribute texture, shape, contrast and colour to the overall garden scheme. It will provide food, protection from predators, nesting sites and shelter from the elements for birds, bees, frogs and other creatures.

The plants should be placed 3 or 4 feet apart. The idea is to have them grow into each other, branches intermingling. The beauty of hedgerows is that they merge with additional plantings in garden beds; with no clear line between what is the hedge and what is the border.

Unify the diversity through a color scheme or repetition that ties everything together.

Traditionally, hedgerows include such things as Rose Rugosa, Mock orange, Little Lime Hydrangea,  Weigela, Spirea, Barberry and many more.

Whether used as a decorative feature, a privacy screen or to help define areas of the garden, hedges add a touch of formality to your outdoor space.

There is no end to the possibilities a hedge can provide. Go ahead, experiment. Plant a hedge, or two or three.
