Why Coastal Front Gardens Need Tough Plants

If you live within sight or sound of the sea, your front garden is doing a job that most inland plots never have to contemplate. It is taking the full force of salt-laden wind, often on thin, sandy or stony soil, with little shelter and no shade to soften the summer sun. Plants that thrive in a sheltered suburban border will sulk, scorch and eventually give up in these conditions — which is why so many coastal front gardens end up as gravel and a lonely fuchsia.

The good news is that salt tolerance and beauty are not mutually exclusive. A carefully chosen framework of salt-tolerant shrubs will give you colour, structure and, just as importantly, a windbreak that makes the rest of the garden possible. The trick is to plant in layers: tough evergreens at the front line, softer flowering shrubs behind them, and a few characterful specimens to draw the eye.

Start With the Windbreak Layer

Before you think about colour, think about shelter. A front garden that faces the prevailing wind — usually south-westerly around much of the British coast — needs a permeable barrier rather than a solid one. Solid fences and walls simply push the wind over the top and create damaging turbulence on the leeward side. Mixed shrubs that filter the wind are far kinder to everything behind them.

• Sea buckthorn (Hippophae rhamnoides) is the classic coastal workhorse, with silvery foliage and orange berries on female plants. It is thorny, so site it away from paths, and give it room — it spreads by suckers.
• Tamarisk (Tamarix ramosissima) shrugs off spray and produces feathery pink flower spikes in late summer. It is deciduous but its fine, airy habit lets wind through rather than snapping.
• Escallonia makes a dense, glossy evergreen hedge that stands up to exposure and clips well. Pink or white flowers appear through summer.

Plant these as a loose, staggered band rather than a tight line. You will lose a little of the view, but you will gain a garden that is genuinely habitable.

Evergreen Structure All Year Round

Once the windbreak is established, you can be more adventurous. Evergreens earn their place in a coastal front garden because they hold the plot together in winter, when deciduous shrubs are reduced to sticks. They also provide the dark backdrop that makes flowering plants sing.

• Hebe comes in dozens of forms, from low cushions to waist-high mounds, and nearly all are happy in salt wind. Hebe pinguifolia and Hebe albicans are particularly tough, with grey-green leaves and white or pale lilac flowers.
• Olearia, the daisy bush, has felted grey foliage that resists salt burn and produces masses of small white daisies in late summer. Olearia haastii is the most reliable in exposed spots.
• Griselinia littoralis is a New Zealand native with thick, apple-green leaves, ideal for a coastal hedge or a rounded specimen. It tolerates wind and light frost but prefers a little shelter inland.

Use these as the bones of the garden, spacing them generously so air can move between them. Crowding evergreens in a windy site invites fungal problems.

Colour That Lasts Through the Season

With shelter in place, you can layer in flowering shrubs that would otherwise struggle. Aim for a sequence of interest rather than a single burst in June.

• Cistus, the rock rose, is made for coastal gardens: silver-grey leaves, papery flowers in white, pink or crimson, and a love of poor, free-draining soil. It is short-lived but self-seeds freely.
• Rosemary is both culinary and ornamental, with blue flowers from late winter and an aroma that carries on the wind. It thrives on dry, chalky or sandy ground.
• Hydrangea may surprise you, but Hydrangea paniculata and the lacecap forms cope well with coastal conditions if given a little shelter and plenty of organic matter at planting time.
• Fuchsia magellanica is the hardiest of the fuchsias and flowers right through to the first frosts, often surviving as a woody shrub in mild coastal districts.

Soil, Planting and Aftercare

Coastal soils are often light, free-draining and low in nutrients, which suits many of these shrubs but means you must water diligently for the first two summers. Dig in well-rotted organic matter — compost, leafmould or manure — at planting time to hold moisture and buffer the salt. A mulch of bark or gravel afterwards will suppress weeds and protect the roots.

Plant in autumn or early spring, when the soil is warm and moist, and stake tall specimens against wind rock. Resist the urge to feed heavily: too much nitrogen produces soft growth that salt wind will shred. A light dressing of a balanced fertiliser in spring is plenty. Prune lightly after flowering, removing dead or crossing wood, and never hard-prune an evergreen into old wood unless you are certain it will reshoot.

Borrowing From Local History

There is a quiet pleasure in planting what the coast has always grown. Along the shingle and dune edges of Britain, sea buckthorn, sea kale and tamarisk have been part of the landscape for centuries — used for stabilising soil, for dye, for food and for shelter. Fishermen's cottages often had a wind-bent fuchsia or a rosemary bush by the door, not for fashion but because they survived.

Look at what thrives in the older gardens along your seafront and let that guide you. A front garden that works with the wind rather than against it will reward you with colour, scent and shelter for decades — and it will look as though it belongs there.
